An 18-year-old mother of a baby boy was shot and killed in a Chicago suburb just hours after her younger sister had sat on the stage behind President Obama, listening to him push for gun control legislation.

MyFoxChicago.com reports two people are being questioned in the shooting death of Janay McFarlane, but no one has been charged. The mother of a 3-month-old baby boy was shot once in the head around 11:30 p.m. Friday in North Chicago while visiting friends and family.

"Every time I think about the way my child died it's hard to think about her dying like that because she didn't deserve it, she didn't deserve dying like that," McFarlane's mother Angela Blakely told MyFoxChicago.com.

Family members reportedly believe the gunman was targeting the friend McFarlane was with when she was shot.

Hours earlier, McFarlane's 14-year-old sister Destini Warren was 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.

"It really hurt me when I find out that it happened to my sister because I was just listening to... I was thinking about her dying when he was saying it and then later on they called me and told me it happened to my sister," Warren told MyFoxChicago.com.

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 and the slaying happened about a mile from his Chicago home.

Blakely said 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.
