Yesterday afternoon, a Brooklyn teenager was shot while entering her Brooklyn apartment building. According to the Daily News, the 17-year-old was "shot once in the back by a gunman aiming for another man...The thug was trying to shoot a young man running inside 3023 Avenue X, part of the Nostrand Houses, when the .22-caliber bullet struck the 17-year-old girl outside her first-floor apartment door." Friends say she was returning home from the store and that she is a student at Sheepshead Bay High School (which is across the street). Her injuries are not life-threatening. And, early on Sunday morning, a man fired into a crowd on a Bronx street; one person was injured and the shooter is still at large.
