Arias Leaves Stand After Describing Killing, Her Lies

Jodi Arias stepped down from the witness stand today after mounting an emotional effort to save herself from death row, insisting to the Arizona jury that an explosive fight with ex-boyfriend Travis Alexander led to his death, and that her lies about killing him masked deep regret and plans to commit suicide.

Arias, 32, will now face what is expected to be a withering cross-examination beginning Thursday from prosecutor Juan Martinez, who has been aggressive to many witnesses throughout the trial and who is expected to go after Arias' claim that she was forced to kill Alexander or be killed herself.

She is charged with murder for her ex-boyfriend's death and could face the death penalty if convicted.

The day's dramatic testimony started with Arias describing the beginning of the fight on June 4, 2008 when she and Alexander were taking nude photos in his shower and she claims she accidentally dropped his new camera, causing Alexander to lose his temper. Enraged, he picked her up and body slammed her onto the tile floor, screaming at her, she told the jury.

Arias said she ran to his closet to get away from him, but could hear Alexander's footsteps coming after her down the hall. She grabbed a gun from his shelf and tried to keep running, but Alexander came after her, she said.

"I pointed it at him with both of my hands. I thought that would stop him, but he just kept running. He got like a linebacker. He got low and grabbed my waist, and as he was lunging at me the gun went off. I didn't mean to shoot. I didn't even think I was holding the trigger," she said.

"But he lunged at me and we fell really hard toward the tile wall, so at this point I didn't even know if he had been shot. I didn't see anything different. We were struggling, wrestling, he's a wrestler.

"So he's grabbing at my clothes and I got up, and he's screaming angry, and after I broke away from him. He said 'f***ing kill you bitch,'" she testified.

Asked by her lawyer whether she was convinced Alexander intended to kill her, Arias answered, "For sure. He'd almost killed me once before and now he's saying he was going to." Arias had earlier testified that Alexander had once choked her.

But Arias' story of the death struggle ended there as she told the court that she has no memory of stabbing or slashing Alexander whose body was later found with 27 stab wounds, a slit throat and two bullets in his head. She said she only remembered standing in the bathroom, dropping the knife on the tile floor, realizing the "horror" of what had happened, and screaming.

"I have no memory of stabbing him," she said. "There's a huge gap. I don't know if I blacked out or what, but there's a huge gap. The most clear memory I have after that point is driving in the desert."

Arias said that she decided in the desert not to admit to killing Alexander, a decision that would last for two years as Arias lied to friends, family, investigators and reporters about what really happened in Alexander's bathroom.

During that time she initially claimed she got lost that night while driving to a friend's house and never went to Alexander's home in Mesa,Ariz. She later changed her story and said two masked people, a man and a woman, burst into the home and killed Alexander and threatened to kill her family if she told anyone what happened.

She eventually confessed to killing her ex-boyfriend, but insisted it was self defense.

"The main reason (for lying) is because I was very ashamed of what happened. It's not something I ever imagined doing. It's not the kind of person I was. It was just shameful," she said. "I was also very scared of what might happen. I didn't want my family to know that I had done that, and I just couldn't bring myself to say that I did that."

"From day one there was a part of me that always wanted to (tell the truth) but didn't dare do that. I would rather have gone to my grave than admit I had done something like that," she said.

Arias said that she continued to lie because she figured she would never get caught; she was planning to kill herself before trial.

"I was concerned with how it would affect my family. I wanted to die. I was going to definitely kill myself," she said. "That was my plan. You can purchase different things in jail and I bought a bunch of Advil... and took it all in the next few days so it was in my system. They have razors for shaving, so I got one and took it apart one night with intentions to slit my wrists."

Arias said she balked at slitting her wrists after accidentally cutting herself, but that she still planned to commit suicide sometime in the future. When she told news reporters that "no jury would convict her," she claims she said it believing that she would be dead before they'd have a chance to put her on trial, Arias testified.

Arias said support from the public and her family eventually led her to change her mind.

"My family remained very supportive, and told me 'it doesn't matter what happens, we love you anyway.' I realized even if I told the truth they would still be there and wouldn't walk away," she testified.

"By the time spring, 2010, rolled around, I confessed. I basically told everyone what I could remember of the day and that the intruder story was all BS pretty much."

She said that her testimony today, a third version of events, was the truth.

Arias was arrested a month after Alexander's death, and prosecutors have argued that her behavior during those weeks showed a lack of remorse for the killing and an attempt to get away with murder.

Arias said today that after she killed Alexander and drove away from his Mesa, Ariz., home in a panic, it dawned on her that police would soon be looking for Alexander's killer, and she decided that she would pretend the bloody confrontation had never happened.

"I knew that it was really bad, that my life was probably done now. I wished it was just a nightmare I could wake up from, but I knew I had messed up pretty badly and the inevitable was going to be something I could not really run from," she testified.

"I didn't want anyone to know that that had happened or that I did it, so I started taking steps in the aftermath to cover it up. I did a whole bunch of things to try to make it seem like I was never there," she said.

Tunisian PM quits after failing to form new government

TUNIS (Reuters) - Tunisian Prime Minister Hamadi Jebali resigned on Tuesday after failing to replace a government pulled apart by acrimony between his Islamist allies and their secular opponents.

Jebali had threatened to quit if his plan for a non-partisan cabinet of technocrats to lead the north African country into early elections foundered.

In the end it was his own party, Ennahda, that rejected the proposal, prolonging the political stand-off that has cast a shadow over Tunisia's fledgling democracy and deepened an economic crisis.

"I vowed that if my initiative did not succeed, I would resign and ... I have already done so," Jebali told a news conference after meeting with President Moncef Marzouki.

Tunisia's deepest political crisis since the 2011 Arab Spring uprising that toppled President Zine El Abidine Ben Ali began when leading secular opposition politician Chokri Belaid was gunned down outside his home in Tunis on February 6.

No one claimed responsibility for the killing, but it deepened the misgivings of secularists who believe Jebali's government has failed to deal firmly enough with religious extremists threatening the country's stability.

Protesters poured onto the streets in the following days and Marzouki's secularist party threatened to quit the coalition government.

Jebali said he would try to form a cabinet of apolitical technocrats to restore calm and take Tunisia to elections, but did not consult his Ennahda allies or their secular coalition partners before making the proposal.

Several secular politicians backed the plan but Ennahda, winner of most parliamentary seats in elections that followed Ben Ali's overthrow, opposed the idea, fearing it would be sidelined from power.

Jebali bet his own job on the outcome, saying he would quit if he was rebuffed, and lost.

He quits 15 months into the job, although political experts said Marzouki was likely to re-appoint him as caretaker premier before a new leader is appointed.

Ennahda leader Rached Ghannouchi has said he wants to see Jebali head a new coalition. President Marzouki was due to meet Ghannouchi on Wednesday to ask him to name a prime minister.

But Jebali, announcing his resignation late on Tuesday, said he would not lead another government without assurances on the timing of fresh elections and a new constitution.

No government would be viable without Ennahda's blessing given its strength in parliament.

Ghannouchi has said it is essential that Islamists and secular parties share power now and in the future, and that his party was willing to compromise over control of important ministries such as foreign affairs, justice and interior.

"Ennahda is in negotiations with political parties to form a national coalition government", said Fethi Ayadi, a senior Ennahda official.

Iyed Dahmani, a leader of the secular Republican Party, said some kind of agreement was vital.

"We are in real trouble, politically and economically," he said.

The crisis has disrupted efforts to revitalize an economy hit hard by the disorder that followed the overthrow of veteran strongman Ben Ali.

Tunisia has been negotiating with the International Monetary Fund for a $1.78 billion loan and politicians said Jebali's inability to re-establish a functioning government had slowed efforts to restore normality.

Credit rating service Standard and Poor's said on Tuesday it had lowered its long-term foreign and local currency sovereign credit rating on Tunisia, citing "a risk that the political situation could deteriorate further amid a worsening fiscal, external and economic outlook".

Pro-family and women-friendly workplaces called for by PAP Women's Wing

Singapore: The Women's Wing of the People' Action Party wants to see bolder government intervention in the drive for pro-family and women-friendly workplaces.

In a position paper submitted to the Ministry of Manpower (MOM) on Wednesday, it called for legislation to allow employees with children below the age of 12-years to request for flexible work arrangements.

Such requests, it said, should be seriously considered by employers.

It's also proposing legislation to allow employees to take no-pay leave for up to one year to take care of their children, and have their positions guaranteed when they return to work.

To champion and implement the necessary Human Resource policy changes, the paper suggested that the government set up a one-stop centre that can also provide training and handle complains.

The Women's Wing also wants to see better protection for freelance and contract workers - to include CPF contributions, medical benefits and injury compensation.

It also suggested a Back to Work Employment credit scheme - similar to the special employment credit scheme for older workers - to offset employers' costs for on-the-job training for women and job redesign.

People's Action Party (PAP) Member of Parliament for West Coast GRC, Ms Foo Mee Har says the government needs to take bold legislative action to ensure a shift towards a pro-family work culture.

Drug overdose deaths up for 11th consecutive year

CHICAGO (AP) — Drug overdose deaths rose for the 11th straight year, federal data show, and most of them were accidents involving addictive painkillers despite growing attention to risks from these medicines.

"The big picture is that this is a big problem that has gotten much worse quickly," said Dr. Thomas Frieden, head of the Centers for Disease Control and Prevention, which gathered and analyzed the data.

In 2010, the CDC reported, there were 38,329 drug overdose deaths nationwide. Medicines, mostly prescription drugs, were involved in nearly 60 percent of overdose deaths that year, overshadowing deaths from illicit narcotics.

The report appears in Tuesday's Journal of the American Medical Association.

It details which drugs were at play in most of the fatalities. As in previous recent years, opioid drugs — which include OxyContin and Vicodin — were the biggest problem, contributing to 3 out of 4 medication overdose deaths.

Frieden said many doctors and patients don't realize how addictive these drugs can be, and that they're too often prescribed for pain that can be managed with less risky drugs.

They're useful for cancer, "but if you've got terrible back pain or terrible migraines," using these addictive drugs can be dangerous, he said.

Medication-related deaths accounted for 22,134 of the drug overdose deaths in 2010.

Anti-anxiety drugs including Valium were among common causes of medication-related deaths, involved in almost 30 percent of them. Among the medication-related deaths, 17 percent were suicides.

The report's data came from death certificates, which aren't always clear on whether a death was a suicide or a tragic attempt at getting high. But it does seem like most serious painkiller overdoses were accidental, said Dr. Rich Zane, chair of emergency medicine at the University of Colorado School of Medicine.

The study's findings are no surprise, he added. "The results are consistent with what we experience" in ERs, he said, adding that the statistics no doubt have gotten worse since 2010.

Some experts believe these deaths will level off. "Right now, there's a general belief that because these are pharmaceutical drugs, they're safer than street drugs like heroin," said Don Des Jarlais, director of the chemical dependency institute at New York City's Beth Israel Medical Center.

"But at some point, people using these drugs are going to become more aware of the dangers," he said.

Frieden said the data show a need for more prescription drug monitoring programs at the state level, and more laws shutting down "pill mills" — doctor offices and pharmacies that over-prescribe addictive medicines.

Last month, a federal panel of drug safety specialists recommended that Vicodin and dozens of other medicines be subjected to the same restrictions as other narcotic drugs like oxycodone and morphine. Meanwhile, more and more hospitals have been establishing tougher restrictions on painkiller prescriptions and refills.

One example: The University of Colorado Hospital in Aurora is considering a rule that would ban emergency doctors from prescribing more medicine for patients who say they lost their pain meds, Zane said.

Arias Says Violent Sex Preceded Killing

Jodi Arias and her ex-boyfriend, Travis Alexander,, had increasingly violent sex in which he tied her to his bed, twisted her arm, bent her over a desk for anal sex, and made sex videos with her in the hours leading up to the stabbing and shooting frenzy that left Alexander dead.

It was a day in which Arias, 32, inched closer to telling the court how the killing of Alexander took place, but after several hours of increasingly emotional testimony the court was adjourned until Wednesday.

In her sixth day on the stand, Arias tearfully described the sex-filled hours that led to Alexander's death on June 4, 2008. She is charged with murder for killing her former boyfriend, but claims she was forced to kill him self-defense. She could face the death penalty if convicted.

"He tied me up, (on) the bed. It's not my favorite but it's not unbearable," Arias told the court.

She said he used a kitchen knife in the bathroom to cut the rope to the proper length, but she didn't remember whether he left the knife in the bathroom or brought it back to the nightstand in the bedroom.

"There are a lot gaps that day... a lot of things I don't remember that day," she said.

Arias and Alexander then took graphic sexual photos of one another and made a sex video, both of which Arias said were Alexander's ideas. Arias has girlish braids in the pictures.

But the mood of the afternoon turned, she said, when Alexander became angry over a scratched computer disk of photos she gave him. He threw the CD and Arias said she became "apprehensive" of his rising temper.

"I know he's getting angry because Napoleon [Alexander's dog] got up and left the room and he always leaves the room when he gets mad." she testified.

"I don't know that I was consciously thinking (of violence) but I was more tense. I stood up, went to walk over to him, to rub his back and make sure he was okay," she said. "But he grabbed me on the upper arms, spun me around and grabbed my right arm and twisted it behind my back, and bent me over the desk, and pressed up against me."

"I was scared he was going to throw me or something, kick me," she continued. "He pressed his groin up against my butt, did a few thrusts and then started pulling my pants down."

The pair then had anal sex, which Arias said pacified Alexander.

"I was very relieved. I felt like we had avoided catastrophe. It could have led to another fight," she said.

Instead of a fight, Alexander, who was 27 and a devout Mormon, and Arias decide to go upstairs and take more nude photos of one another. Arias said she hoped the photos would satisfy Alexander over his frustration with the scratched CD.

Evidence introduced earlier in the trial show that Alexander was killed while Arias was photographing Alexander in the shower.

Timeline of the Jodi Arias Trial

Earlier, Arias explained that she wasn't planning to visit Alexander during her roadtrip from her home in California, but was convinced by him to spontaneously take a detour to his house for sex and to hang out.

"The very last time I called Travis it was kind of like, I don't know how to describe it, he had been very sweet and was guilting me and making me feel bad that I was taking this big trip without going to see him," Arias said this afternoon.

"When I called him last time it was just like all right, I'm going," she said. "(Sex) was our thing at that time. I wasn't going to go there, stay the night and not do that."

Arias' attorney, Kirk Nurmi, asked her repeatedly on the stand if Arias brought a gun or knife with her on the roadtrip and to Alexander's house. She said that she did not.

She also denied a series of allegations made by the prosecution that she dyed her hair, rented an inconspicuous car, borrowed gas cans, turned off her cell phone, and switched money around her bank accounts as she left for Alexander's house because she was planning to murder him when she got there.

Arias said that her hair remained the same color, auburn-brown, throughout May and June, that she rented a car because her own car was not stable enough for highway travel, that she requested a white car instead of a red one because police pull red ones over more often, and that she transferred money to a business banking account for a tax write-off to classify it as a business trip.

The testimony about the road trip and Arias' planning could be key to the jury as they decide whether the killing was pre-meditated, as the prosecution claims. Arias could face the death penalty if convicted of murder with aggravating factors such as pre-meditation.

Arias said that she "didn't sleep at all last night" before testifying about the dramatic incident today. Her comment was stricken from the record.

Arias also described a barrage of threatening text messages sent by Alexander in which he told her he would exact "revenge" on her soon and called her a "sociopath."

She told the court that Alexander's temper would make her "cower."

The messages show a growing discord between the pair in April 2008, less than two months before Arias killed Alexander.

Chavez back in Venezuela, on Twitter with four million followers

CARACAS (Reuters) - After Hugo Chavez spent two months out of the public eye for cancer surgery in Cuba, the Venezuelan government hailed his homecoming on Monday and said the president had achieved another milestone - 4 million followers on Twitter.

The 58-year-old flew back from Havana before dawn and was taken to a military hospital. No new details were given on his health, and there were no images of his arrival. Officials say his condition remains delicate.

The normally loquacious socialist leader, who is struggling to speak as he breathes through a tracheal tube, took to Twitter with a passion back in April 2010, tweeting regularly and encouraging other leftist Latin American leaders to do likewise.

His @chavezcandanga account quickly drew a big mixed following of fans, critics and others just curious to see how his famously long speeches and fiery anti-U.S. invective would work within the social media network's 140-character limit.

But as he fought the cancer and underwent weeks of grueling chemotherapy and radiation therapy, he began to tweet less and less frequently, before stopping altogether on November 1.

Early on Monday morning, he made his reappearance.

"It was 4:30, 5 a.m. He got to his room and surprised everyone: rat-tat-tat, he sent three or four messages, and at that moment fireworks began to go off around the country," Vice President Nicolas Maduro said in a televised cabinet meeting.

During the day, Maduro added, the president's number of followers had shot up to well over four million.

"It's incredible, in just a few hours ... he's the second most-followed president in the world (after Barack Obama), and the first if we make the comparison by per capita," he said.

Obama has more than 27 million Twitter followers and is No. 5 most followed globally. Chavez is Twitter's No. 190 globally.

4TH MILLION FOLLOWER

Maduro said Chavez's four millionth follower was a 20-year-old single Venezuelan woman named Alemar Jimenez from the gritty San Juan neighborhood in downtown Caracas, near the military hospital where the president arrived earlier in the day.

"She's one of the golden generation of youth who support the fatherland and have been waiting with growing love for commander Hugo Chavez," Maduro said, before presenting a dazzled-looking Jimenez to the cameras and giving her a bunch of flowers.

"We were really emotional" she said, recounting how she was with her mother when they heard Chavez had returned. "I sent him a message on Twitter saying he must get better."

There are still big questions over the president's health. He could have come back to govern from behind the scenes, or he may be hoping to ease political tensions and pave the way for a transition to Maduro, his preferred successor.

Chavez has often ordered followers to fight back against opposition critics of his self-styled revolution by using social media, leading from the front himself on Twitter and referring to the Internet as a "battle trench."

As his ranks of followers grew, Chavez said he hired 200 assistants to help him respond to messages - which he said were a great way to receive first-hand the requests, demands, complaints and denunciations of citizens in the thousands.

During his re-election campaign last year, the government launched an SMS text message service that forwards his tweets to cellphones that lack Internet service, broadening their reach to the poorest corners of the South American country.

"He's a communication revolution!" Maduro said, later unbuttoning his shirt on TV to show he was wearing a T-shirt bearing Chavez's eyes emblazoned across his chest.

For the tens of thousands who signed up on Monday to follow Chavez on Twitter, it is unclear how much will be posted there in the weeks and months ahead. Venezuela's 29 million people are mostly wondering something similar.

Hold panchayat polls as per existing quota: SC to Andhra Pradesh

NEW DELHI/HYDERABAD: The Supreme Court on Monday cleared the decks for elections to the panchayati raj (PR) institutions in the state and an upbeat chief minister Kiran Kumar Reddy wants to hold the polls at the earliest. With state election commissioner P Ramakanth Reddy stating that his department is fully prepared, the PR polls, touted as an acid test for the chief minister as well as new entrant YS Jaganmohan Reddy, could be held as early as April this year.

In its judgment on Monday, the SC bench of Justice P Sathasivam and Justice J S Khehar directed the state to conduct the polls on the basis of the existing 60.5% reservation for BCs (34%), SCs (18.25%) and STs (8.25%). Following a petition challenging the quota as exceeding the limit fixed by the apex court, the AP High Court had directed the state to hold the PR polls by fixing 50% as upper limit of the quota for the BCs, SC-STs . Monday's decision of the Supreme Court was on the basis of an appeal filed by the state government against the HC order.

Kiran Kumar Reddy's optimism of the Congress putting up a good performance is based on the public assurance given by Union panchayat raj minister Kishore Chandra Deo in Delhi soon after the SC verdict on Monday that Rs 2,400 crore that was held up for the last two years for providing drinking water and sanitation in rural areas will be released as soon as the local bodies are in place. "Assured of the funds, the CM can sway the voters in Congress' favour by announcing several welfare schemes," averred political analysts.

The term of the panchayati raj institutions, namely 1,094 zilla parishad territorial constituency (ZPTC) members , 14,591 mandal parishad territorial constituency members (MPTC), and 21,843 sarpanches , ended in July 2011 and since then, they have been under the control of special officers in the absence of elected councils. The PR polls could not be held till now as the issue was pending in the court.

Confident that he will be flush with funds, the chief minister has directed the concerned departments to be ready for the polls at the earliest . "Jagan is in jail. Telangana is calm. The state government is politically stable. And summer is far away. All this should work in Congress favour ," said a senior Congress leader.

Deo promises to release blocked funds

Although the recently held primary agricultural cooperative societies polls were not party-based , the Congress has claimed that it won a majority. In fact, the Congress claims that candidates owing allegiance to it won the elections even in Telangana, much to the chagrin of TRS and other parties .

The PR polls will be party based and the opposition parties, including the YSR Congress, TDP, TRS, BJP, Left parties and Lok Satta welcomed the SC order and wanted the state to hold the local body elections immediately. Jagan is confident that the polls will prove that he has mass following, while the TDP believes that the elections will pave the way for its leader Chandrababu Naidu's return to power. Panchayat raj department officials said they would initiate the process of delimitation of the constituencies and fixing quota in a week. State election chief Ramakanth Reddy told the media in Delhi that the commission would launch its process once it receives the data from the government.

Welcoming the SC decision, Union panchayat raj minister Kishore Chandra Deo announced that he would release the amount withheld as per the Constitution. "We have withheld Rs 2400 crore in the past two years, meant for providing drinking water and sanitation for rural areas, as there were no local governing bodies. We will release the amount once the local bodies are in place," Deo told media in Delhi.

Hip implants a bit more likely to fail in women

CHICAGO (AP) — Hip replacements are slightly more likely to fail in women than in men, according to one of the largest studies of its kind in U.S. patients. The risk of the implants failing is low, but women were 29 percent more likely than men to need a repeat surgery within the first three years.

The message for women considering hip replacement surgery remains unclear. It's not known which models of hip implants perform best in women, even though women make up the majority of the more than 400,000 Americans who have full or partial hip replacements each year to ease the pain and loss of mobility caused by arthritis or injuries.

"This is the first step in what has to be a much longer-term research strategy to figure out why women have worse experiences," said Diana Zuckerman, president of the nonprofit National Research Center for Women & Families. "Research in this area could save billions of dollars" and prevent patients from experiencing the pain and inconvenience of surgeries to fix hip implants that go wrong.

Researchers looked at more than 35,000 surgeries at 46 hospitals in the Kaiser Permanente health system. The research, published Monday in JAMA Internal Medicine, was funded by the U.S. Food and Drug Administration.

After an average of three years, 2.3 percent of the women and 1.9 percent of the men had undergone revision surgery to fix a problem with the original hip replacement. Problems included instability, infection, broken bones and loosening.

"There is an increased risk of failure in women compared to men," said lead author Maria Inacio, an epidemiologist at Southern California Permanente Medical Group in San Diego. "This is still a very small number of failures."

Women tend to have smaller joints and bones than men, and so they tend to need smaller artificial hips. Devices with smaller femoral heads — the ball-shaped part of the ball-and-socket joint in an artificial hip — are more likely to dislocate and require a surgical repair.

That explained some, but not all, of the difference between women and men in the study. It's not clear what else may have contributed to the gap. Co-author Dr. Monti Khatod, an orthopedic surgeon in Los Angeles, speculated that one factor may be a greater loss of bone density in women.

The failure of metal-on-metal hips was almost twice as high for women than in men. The once-popular models were promoted by manufacturers as being more durable than standard plastic or ceramic joints, but several high-profile recalls have led to a decrease in their use in recent years.

"Don't be fooled by hype about a new hip product," said Zuckerman, who wrote an accompanying commentary in the medical journal. "I would not choose the latest, greatest hip implant if I were a woman patient. ... At least if it's been for sale for a few years, there's more evidence for how well it's working."

Obama's Speech on Guns Doesn't Stop Ill. Killing

A Chicago teenager was shot and killed Friday only hours after her sister attended President Obama's speech on the city's rampant gun violence.
Janay McFarlane, 18, was killed while walking with a friend during a visit to her dad, Herbert McFarlane, in North Chicago.

"All this gun violence going on, you never think it would be your child," he told ABC's Chicago station WLS. "This is the hardest thing for me in my life."

Herbert McFarlane told WLS that the loss of Janay is especially hard because she leaves behind a 3-month old son, who likes to wear an "I love Mommy" shirt. The shooting occurred in Lake County, a northern suburb miles from the epicenter of the gun violence on the city's South Side.

"I'm in Lake County to get away from violence and now it happened in Lake County where I moved to," he told WLS.

McFarlane and her child spent time both in Lake County and on the South Side where her mother lives.

Only hours before McFarlane was shot and killed, President Obama returned to his hometown to speak on the South Side at a Hyde Park high school. McFarlane's sister, Destini Warren, 14, sat behind the president during the speech.

More than 500 people were shot and killed here last year, and this year the situation has worsened with the most deadly January the city has seen in over a decade. The shooting death of Hadiya Pendleton, a 15-year old who performed in Washington, D.C. at events connected to the president's inauguration last month, garnered national attention.

"Too many of our children are being taken away from us," Obama said in Hyde Park, with McFarlane's sister in the audience.

"Last year there were 443 murders with a firearm on the streets of this city, and 65 of those victims were 18 and under," he said. "So that's the equivalent of a Newtown every four months." He was referring to Newtown, Conn., where 20 first graders were gunned down by Adam Lanza along with seven adults.

Only hours later in Chicago, another 18-year old was shot and killed.

"I felt like someone took a knife and stabbed me in the heart, and a piece of my heart I will never get back," Angela Blakely, Janay McFarlane's mother, told WLS.

North Chicago Police on Sunday reportedly questioned two people in connection to McFarlane's death. Her family said McFarlane was an unintended target of the shooting.

Messages left by ABC News with the North Chicago Police Department and the Lake County Coroner's Office went unreturned Monday.

Another Chicago teenager, Frances Colon, was also shot and killed Friday just hours after she had told her father that she saw President Obama's helicopter fly over her neighborhood.
