Police say the 31 year-old woman was walking with her 5-year-old daughter outside their apartment building when a bullet tore into her shoulder.
One witness says the neighborhood is no stranger to violence.
"All the time, at least once a week there's something going on here," he said. "Two weeks ago there was a stabbing. Every other day, like twice a week, there's fight going on. It's a lot of gang violence in the area too so that's probably the situation."
Investigators say they don't believe the woman was the intended target. Her daughter was not hurt.
