Four people were shot, two fatally, and at least two others were stabbed Monday night in an outbreak of violence in a South Philadelphia neighborhood, police said.

Police said some sort of dispute that began in a residence on the 2100 block of Bailey Terrace and spilled into the street left two people with stab wounds and preceded two separate shootings within 90 minutes.

The first shooting occurred about 9:50 p.m., when a gunman opened fire outside a residence in the Wilson Park Homes, hitting two women and a man, police said.

A 42-year-old woman who had been shot in the head and neck was taken to Penn Presbyterian Medical Center, where she died, police said. Police Commissioner Richard Ross told 6ABC that the woman, whose name was not immediately released, was not involved in the original dispute and “appears to have just been a neighbor.”

A 51-year-old woman with a gunshot wound to her thigh and a 59-year-old man who had been shot in his buttock were taken to Hahnemann University Hospital and were expected to recover, police said. Ross said, they too, did not appear to have been involved in the initial altercation.

Police said a 40-year-old woman and a 35-year-old man were stabbed in the initial dispute. Both were in stable condition at the Hospital of the University of Pennsylvania.

About 11:20 p.m., gunfire rang out around the corner, on Point Breeze Avenue, and police who were still at the scene of the first shooting found a 24-year-old man who had been shot multiple times. He was taken to Penn Presbyterian and pronounced dead at 11:48 p.m., police said.

Ross told 6ABC the victim had been seen at the original dispute but it was not clear if or how he was involved.

There was some confusion about the role — if any — of another man police said had been stabbed.

Chief Inspector Scott Small told reporters at the scene that police took the 26-year-old man into custody after he arrived at a hospital and acted suspiciously.

A witness later identified the man as the gunman, Small said.

But in a later summary of the incident, police made no mention of a 26-year-old stabbing victim and listed the offender as unknown.
