Janay McFarlane, 18, was shot on the way to a store, the same day Obama spoke on gun violence. 
  
 Two men are being questioned in connection with the fatal shooting of an 18-year-old Chicago woman Friday, the same day her younger sister attended President Barack Obama's speech on gun violence, officials said. 
  
 The pair, 18 and 20, are being questioned by North Chicago police and officials from the Lake County state's attorney's office in connection with the death of Janay McFarlane, according to a statement released Sunday by North Chicago police. 
  
 The men were arrested after McFarlane was shot about 11:30 p.m. Friday on the 1300 block of Jackson Avenue in the northern suburb. 
  
 McFarlane, 18, of the 8900 block of South Lowe Avenue, was in North Chicago visiting family and friends and was walking with friends when she was shot, said her mother, Angela Blakely. One of the friends may have been the intended target, Blakely said. 
  
 Blakely said she knew few details about the investigation but was encouraged by the news. 
  
 "I'm just hoping that they do find out who did this to my baby so they can pay for the crime they committed," she said. 
  
 McFarlane was killed hours after her sister, Destini Warren, 14, had attended Obama's speech against gun violence Friday. 
  
 North Chicago officials said McFarlane's killing is the first in the northern suburb since October. The October slaying was the only homicide for the town last year. 
  
 Meanwhile, the mother of a murdered Chicago teenager whose death became the focus of the debate about gun control and gun violence on Chicago's streets is appearing in a video public service announcement asking Congress to work for "common sense" reform of the nation's gun laws. 
  
 Cleopatra Cowley-Pendleton asked for background checks on all gun sales in the 30-second spot for Mayors Against Illegal Guns, a coalition founded in 2006 by the mayors of 15 U.S. cities to fight illegal guns on city streets. 
  
 Pendleton's daughter Hadiya Pendleton, a 15-year-old sophomore at King College Prep High School on the South Side, was shot and killed Jan. 29 a few blocks away from the school. A little more than a week before her death, the teen had been in Washington to perform during festivities surrounding Obama's inauguration.

 Two more CPS students were killed during aweekend that began with a visit from the president to bemoan Chicago’s violent streets. 
  
 Frances Colon, 18, a senior at Roberto Clemente High School, was gunned down Friday night in the 1100 block of North Pulaski. She was the unintended target of a shooter, Chicago Police said Sunday. 
  
 And Oscar Marquez, 17, a junior at Marine Math and Science Academy and the eldest of four children, died Saturday night after a gunman opened fire on the car carrying Marquez home from a shopping trip. 
  
 Six other people were injured in shootings since Friday night. 
  
 Judith Vazquez, who serves on Clemente’s Local School Council, called Colon’s death tragic and denounced all the recent shootings in which children have been killed. 
  
 “This is happening citywide, not just on the South Side, not just in Hyde Park where the president lives,” she said referring to the fatal shooting of Hadiya Pendleton, 15, a mile from the President Barack Obama’s house a week after she had performed in inauguration events in Washington, D.C. “The violence is bad citywide. It’s affecting the kids as a whole.” 
  
 Frances Colon was shot in the shoulder about 7 p.m. in the 1100 block of North Pulaski, police said. 
  
 “This girl was on track,” Vazquez said, referring other questions to the school. 
  
 Colon, of the 2900 block of West Armitage, was pronounced dead at Mount Sinai Hospital at 8:16 p.m. Friday, according to the Cook County medical examiner’s office. An autopsy on Saturday found that she suffered a fatal gunshot wound in her back and her death was ruled a homicide, according to the medical examiner’s office. 
  
 Her family could not be reached Sunday. 
  
 Oscar Marquez was returning from buying shoes at a local mall with his cousin when he was shot, his mother, Concepcion Marquez said Sunday in her Tri-Taylor neighborhood home in the 700 block of South Oakley. 
  
 His 18-year-old cousin, who was driving the car, was wounded in the arm, she said, and he was expected to be OK. 
  
 The cousins were near Western and Cermak about 6:15 p.m. Saturday when a gunman drove up, got out of his vehicle and fired on them, police said. They drove to Rush University Medical Center, but by the time they arrived, Marquez had died, authorities said. 
  
 Concepcion Marquez, holding her 18-month-old son in her apartment Sunday afternoon, said she didn’t know who shot her son and police hadn’t told her much. Relatives and friends filled the living room; more continued to drop by. 
  
 Oscar liked the Marine Academy and thought about enrolling in the Marine Corps after graduation, she said. Many of his cousins went to school with him, she said, adding that her son was not in a gang. 
  
 Fabian Lopez, a fellow junior at the school, said his friend was good at basketball and adored soccer — and despite the Marine Academy’s strict uniform code, wild soccer haircuts, too. 
  
 “It’s kind of hard to believe that he’s gone,” Lopez said.

 Janay Mcfarlane was shot once in the head around 11:30 p.m. Friday in North Chicago, Lake County Coroner Thomas Rudd told the Chicago Sun-Times. Mcfarlane, the mother of a 3-month-old boy, was in the Chicago suburb visiting friends and family. 
  
 North Chicago police said two people are being questioned in connection with Mcfarlane's death, but no charges have been filed yet. 
  
 "I really feel like somebody cut a part of my heart out," Angela Blakely, Mcfarlane's mother, said. 
  
 Blakely said the bullet that killed Mcfarlane was meant for a friend. 
  
 Hours earlier, Mcfarlane's 14-year-old sister sat feet from Obama at Hyde Park Career Academy, where he spoke about gun violence and paid tribute to Hadiya Pendleton, the 15-year-old honor student fatally shot last month in a South Side park. Police have said it was a case of mistaken identity, and two people have been charged. 
  
 Pendleton's death was one of more than 40 homicides in Chicago in January, a total that made it the deadliest January in the city in more than a decade. Pendleton, a drum majorette, had recently performed during Obama's inauguration in Washington and the slaying happened about a mile (1.6 kilometers) from his Chicago home. 
  
 Blakely told the newspaper that Janay Mcfarlane had been affected by Pendleton's death. 
  
 "She always said after Hadiya Pendleton got killed, 'Momma that's so sad,'" Blakely said. "She was always touched by any kid that got killed. She was always touched by mothers who couldn't be there for their babies because they were gone." 
  
 Mcfarlane was supposed to graduate from an alternative school this spring, Blakely said, and wanted to go into the culinary arts. 
  
 "I'm just really, truly just trying to process it _ knowing that I'm not taking my baby home anymore," Blakely said. |||||

A Chicago teenager was gunned down just hours after her 14-year-old sister sat on a stage behind President Obama as he gave a speech at her high school about gun violence. Janay McFarlane, the 18-year-old mother of a 3-month-old boy, was shot dead while visiting friends and family in North Chicago, the AP reports. Police are questioning two men aged 18 and 20 in connection with the shooting, which happened as McFarlane was walking with friends, reports the Chicago Tribune. In his speech, Obama paid tribute to Hadiya Pendleton, the 15-year-old Chicago girl shot dead days after performing at his inauguration. After Hadiya's killing, McFarlane said, "Momma, that's so sad,'" her mother says. "She was always touched by any kid that got killed. She was always touched by mothers who couldn't be there for their babies because they were gone." In the two days after Obama made his Chicago speech, two other teenagers were shot dead in the city in separate incidents, reports the Chicago Sun-Times.
