PHILADELPHIA (CBS) — Police are investigating after a triple shooting leaves a woman dead and two men injured outside of a West Philadelphia bar and grill.

It happened outside Galaxy West Bar & Grill at 52nd and Market Streets shortly before 4:30 p.m. Sunday.

Police believe 23-year-old Dominique Oglesby was entering the bar to place a food order when an argument ensued.

That’s when police say Oglesby was shot once in the back. She was transported to Penn Presbyterian Medical Center where she later died.

Two male victims were also shot, say police. A 42-year-old man was shot in the foot and a 60-year-old man was shot in his left arm. Both men are listed in stable condition at Penn Presbyterian Medical Center.

Police say the suspect is known to them, but they are not ready to give a name at this point.

The identities of the two male victims have not been released at this time.

Authorities say a weapon has not been recovered and no arrests have been made.
