"They rolled two windows down and two guns came out of the windows and...they started shooting," said Adriane Brown, who owns the home that was shot up on South 65th Street.
The shooting happened around 1 a.m. while 10 people inside the home, including six children, were watching TV.
More than 30 bullets were fired by gunmen in a dark-colored sedan.
One of the bullets hit Brown's 13-year-old great niece in the shoulder. She was visiting the home at the time.
"All I heard was yelling that, 'Aunt Cookie, I'm shot, I'm shot.' And I just started screaming," said Brown. "I was like, 'Who else is hurt? I need to know what's going on.'"
No one else was hit by the gunfire. The teen was rushed into surgery and is expected to physically recover.
Brown said the shooting happened after a former boyfriend, who was being chased by the suspected shooters, ran to her home for safety.
"He ran here and just pushed in, and when he pushed in they started shooting," Brown said.
He was interviewed by police and is cooperating.
So far in 2023, 15 children 13 or younger have been shot in Philadelphia. Two have died from their wounds.
