CHICAGO — An 18-year-old Chicago woman was killed the same day her sister had sat on the stage behind President 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 said. Mcfarlane, a mother of a 3-month-old boy, was in the Chicago suburb visiting friends and family.
