A 22-year-old woman was fatally shot Thursday night while answering the door of her home in West Philadelphia, police said.
The woman was responding to a knock about 7 p.m. in the 5800 block of Walton Avenue when she was shot once in the chest by an unidentified male, said Chief Inspector Scott Small.
Her 4-year-old son was in the house but was not hurt, Small said.
Officers drove the woman to Penn Presbyterian Medical Center, where she was pronounced dead at 7:37 p.m.
Two adult relatives in the house said they did not hear any argument before the shooting, Small said.
