There are now three men aged 18, 19 and 20 in the hospital.
Police say they found the 18-year-old victim on Saturday just before 6pm on Glenlock and Pratt streets.
He had several shots, including two bullets to the chest.
“However, based on information from the victims, it appears that there were several shooters,” said Philadelphia Police Department inspector DF Pace. “Looks like it was a pre-arranged meeting at this place.”
For police, guarding the crime scene was a race against time, as incredibly strong winds threatened to carry away 18 shell casings found on the street.
“We believe the motive for the shooting was drug-related,” Pace said. “The victims are known to the police, and it seems to be a drug deal.
Officials say they have found that two more victims were taken by private car to local hospitals and are in stable condition.
The 18-year-old victim, who is listed as very serious, is now in stable condition.
“We are doing our best to make sure that our investigators are monitoring each investigation, conducting an investigation as thoroughly as possible to be able to identify who the shooters are, and to make sure they are brought to justice,” Pace added.
Police are still looking for videos from local surveillance that could have recorded the incident.
There have been no detentions so far.
