The violence erupted around 6:30 p.m. Saturday near the intersection of East 29th Street and 10th Avenue.
Children nearby gasped in horror at the sound of rapid gunfire. They were just about to sing Happy Birthday to their 13-year-old friend at her backyard party, but instead of blowing out the candles, they ducked for cover when they heard gunshots in the distance.
"Just hearing it - it was scary to witness, to hear. Especially on my birthday. Like a time I'm trying to play with my friends, get together," said the 13-year-old.
She also says she had a friend who was there who saw what happened.
"He was going to the bodega - he went running back, but he had saw two people come out of a car and then shoot, but it was like an automatic gun," she added.
Bystanders watched in shock and panic as first responders treated the victims. One of them was lying in the street next to a car and another was on the ground next to a bicycle.
Local councilman Luis Velez says the City of Paterson has taken measures to reduce crime in this part of town - what he calls a 'hotspot' -- in part by installing security cameras. He is encouraging the community to cooperate.
"Paterson Police is doing their job as I know, they're doing a great job to reduce crime, but one again we, the police, nobody, not even the news media has a crystal ball to say this is going to happen now," Velez said, "Some people see corners getting built up, they see activities and they're afraid to come out and say something, but our police department is trained to keep it confidential and approach to bring the quality of life in this area."
The 13-year-old hopes her next birthday party is not ruined by the sound of gunshots.
"First we thought it was fireworks, but then we heard sirens and everyone started going home because they were scared," she added.
