More than 50 shots were fired when gunfire erupted shortly before midnight on the 600 block of Perth Place.
"It sounded like there was a gun battle back here," according to resident Alex Gonzalez.
Authorities believe there was an exchange of gunfire at the scene. Six men and one woman were shot, all in their 20s, with the exception of a 58-year-old man.
"It sounded like a war zone," said one resident, who did not provide his name.
He added, "When I peeked out the window, I saw a girl. She was limping. You seen her running, you just seen her fall. Then you see her get up and limp."
Bullets struck homes and at least four parked cars.
A bullet pierced the window of the home where Alex Gonzalez lives with his family.
"My mother is in this bed. My mom is paralyzed. It could have hit her," Gonzalez pointed out.
A large amount of cash was strewn across the ground. Dice and guns were left behind.
"At this time, we don't know the motive for the shooting. We don't know if there was a robbery since there's so much cash laying in the courtyard. We don't know the motive at this time," according to Philadelphia Police Chief Inspector Scott Small.
Police arrived within minutes and initially thought there were six victims who arrived to Temple University Hospital and Jefferson University Hospital on their own.
Of the surviving victims, a 22-year-old man is in critical condition and five others are stable.
While police were investigating the crime scene, they discovered a man's body on the 600 block of North 8th Street.
He was pronounced dead on the scene around 2:20 a.m.
"We also know that there are some cameras in the neighborhood. We're trying to determine now if these cameras recorded anything that could help us with this shooting," Small said
