CHICAGO (AP) — An 18-year-old Chicago woman was killed the same day her sister had sat on the stage behind President Barack Obama, listening to him push for gun control legislation.

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 (http://bit.ly/12Uoh9b). Mcfarlane, a 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.
