One man was killed and another injured when gunfire erupted on the 3900 block of North Percy Street, in Philadelphia's Hunting Park neighborhood, Monday evening.
The violence broke out about 6:40 p.m.
Brian Sweet, 20, was pronounced dead at Temple University Hospital at 6:49 p.m., police said.
A second victim — a 22-year-old man who reportedly is Brian Sweet's older brother — sustained a gunshot wound to his right shoulder. He was being treated at Temple, and was listed in critical condition.
It appears an argument led to the gunfire, police said.
