Boston Police say the 12-year-old was injured during an apparent barrage of bullets outside her Whitman Street home around 8:30 p.m. on Monday.
One of the bullets pierced the wall of her home and hit her in the leg, police say, adding she was taken to Boston Medical Center and is expected to recover.
Police say the shooter may be one of several males spotted running from the rear parking lot of Dorchester High School and then getting into a late-model brown Cadillac that drove on Edson Street toward Norfolk Street. The city's ShotSpotter system detected the sound of gunfire about that time on Edson Street, police say, adding that several vehicles and homes suffered bullet damage during the onslaught.
"I am outraged by the cowardice demonstrated by the violent individuals responsible for this senseless act, Police Commissioner Ed Davis said. "Their total disregard for human life resulted in a tragic injury to a child."
