A witness told police they had heard gunshots and saw a man fall to the ground.
A 58-year-old man was found with gunshot wounds to the chest. Investigators say the victim may have been shot in the alley and made his way to the front of a residence before collapsing.
He was transported to Christ Medical Center where he was listed in critical condition and was later pronounced dead.
