About 20 gunshots were fired at the scene. One of the bullets grazed a 72-year-old woman in the stomach as she was leaving her house, investigators said.
Another stray bullet took the life of a resident's dog.
Both men are facing a slew of charges, including aggravated assault.
Branco was also charged with the straw purchasing of 11 firearms, three of which turned up in criminal cases around the city, the DA's office said.
"These arrests send a clear message to those who terrorize our community and traffic guns that they will be held accountable for their willful disregard for public safety," said DA Larry Krasner.
No other injuries were reported in the shooting.
Branco is scheduled for a preliminary hearing on August 30, 2024, and Mazza is scheduled for his preliminary hearing on September 6, 2024.
