PHILADELPHIA (WPVI) -- Three people were killed and another person remains in critical condition after more than 50 shots were fired in the Mayfair section of Philadelphia, police say.
It happened around 10 p.m. Monday near Rowland and Guilford street, not far from Lincoln High School.
Surveillance video shows the suspects getting out of a waiting minivan with guns drawn. They immediately start firing towards four men, who police say had just come back from a trip to the mall.
The victims were 18, 19, 24, and 28 years old. They were ambushed by the gunmen who had been waiting in the parked minivan for about 20 minutes.
Sources close to the investigation say this incident may have been a shooting motivated by drugs.
Police say they marked more than 50 bullet casings on the ground. After they were hit, some of the victims were run over by the shooters who drove off in the same van.
Investigators say the 18- and 19-year-old victims died at the scene.
"There was two people laying in the middle of the street that they weren't doing anything with, they were dead. And then they came later and covered them up," said neighbor John Sullivan.
The 24-year-old was rushed by private car to a Nazareth Hospital where he was pronounced dead.
"One guy was on the ground but he was still moving. I think somebody picked him up and put him in the truck and tried to get him into the hospital," said neighbor Antonio Wade.
The 28-year-old victim got to a nearby house where medics transported him to the hospital. He is in critical condition.
Police are still investigating what led up to the shooting. No arrests have been made.
Police in the 15th district are holding a town hall meeting to address this incident at 7 p.m. Thursday at Lincoln High School.
Anyone with information is asked to call police at 215-686-TIPS.
