Police on Saturday identified the girl as Tynirah Borum. She was shot in the chest by a stray bullet while getting her hair braided at about 9:40 p.m. Friday in the Grays Ferry section of the city, according to police. Officers put her in their patrol car and rushed her to the hospital, where she was pronounced dead less than an hour later.
Three adults were injured, one critically.
"She was everything to us," Renee Bradford, a friend of Tynirah's mother, told WCAU-TV. "She didn't deserve this. She was simply trying to get her hair done. For her to get shot in the chest? She's a baby. No baby deserves to die like that."
Police said Saturday they are speaking with a person of interest. No arrests have been made.
Police said the gunfire erupted during an argument between a man on a bicycle and a 24-year-old man. The cyclist fired three shots from a handgun, shooting the other man in the head, police said. The victim was taken to the hospital in critical condition.
Stray bullets hit Tynirah, a 28-year-old female bystander shot in the left arm and a 21-year-old male bystander shot in the right leg.
Witnesses said the shooter fled on the bike.
"There's nothing much you can say about this tragedy," Mike Collins, the victim's cousin, told the news station. "That was my little cousin. It hurts."
