WILLOW GROVE, Pa. (CBS) — A wheelchair-bound Montgomery County man is headed to state prison for at least five years for firing a gun into a crowd at an Upper Moreland apartment complex last summer, injuring two people including his mother.

Lorenzo Sims pleaded guilty to a felony aggravated assault charge and was sentenced to 5-11 years behind bars.

Witnesses told police the 23-year-old man was holding the gun in his right hand while pushing his wheelchair with his left hand last August at the Willow Hill Apartments when he fired at the man whom police say was his intended target.

“There was an argument between the defendant and the victim over… drugs is what it really amounts to,” says Montgomery County prosecutor Matthew Quigg.  “And they’re going back and forth.   The defendant threatened to shoot the victim when the victim said, ‘You never pulled a trigger a day in your life.’ ”

That’s when Sims fired, seriously injuring the man.

Sims’ mother was caught in the crossfire and was shot through the hand.

Authorities say Sims has a long criminal history and is a convicted felon who shouldn’t have had a weapon.
