Chicago woman Janay Mcfarlane, 18, was killed the same day her sister sat behind President Barack Obama as he pushed for gun control legislation.
Mcfarlane was shot in the head around 11:30 p.m. Friday in North Chicago. The mother of a 3-month-old boy was visiting friends and family.
North Chicago police said two people are currently being questioned in connection with Mcfarlane's death, but no charges have been filed.
"I feel like somebody cut a part of my heart out," her mother Angela Blakely said.
Blakely believes the bullet that killed Janay Mcfarlane was meant for a friend.
Just hours earlier, Mcfarlane's 14-year-old sister was feet from President Obama at Hyde Park Career Academy, where he spoke about gun violence.
In his speech that day, Obama paid tribute to the late Hadiya Pendleton, a 15-year-old honor student fatally shot last month in a South Side park.
Cops say it was a case of mistaken identity; two people have been charged.
Pendleton's death was one of more than 40 homicides in Chicago in January, making this the deadliest January in the city in more than a decade.
Pendleton, a drum majorette, had recently performed during Obama's inauguration; the slaying happened about a mile from his Chicago home.
Janay Mcfarlane had been affected by Pendleton's death, her mom said.
"She always said after Hadiya Pendleton got killed, 'Momma that's so sad,'" Blakely told the Sun-Times. "She was always touched by any kid that got killed."
"She was always touched by mothers who couldn't be there for their babies."
"I'm just really, truly just trying to process it ... knowing that I'm not taking my baby home anymore," a despondent Blakely said of burying her own child..
