One man was killed while five others were hurt in a shooting in Southwest Philadelphia Sunday night that police say took place as people prepared to shoot a rap video.

The six men were outside a house on the 2600 block of Carroll Street around 8:20 p.m. when an unidentified gunman opened fire.

Philadelphia Police Commissioner Richard Ross said the victims were part of a group that was gathered to begin filming a hip-hop video.

"The victims were on the step down the street as we understand it," Ross said. "They were about to shoot a rap video. This is from the witness we have. We have nothing more than that."

A 21-year-old man was shot in the head and pronounced dead at 8:40 p.m. by a medic at the scene. He has yet to be identified.

Five other victims were taken to the Penn Presbyterian Medical Center.

A 22-year-old man who was shot in the finger is in stable condition and another 22-year-old man who was shot in the right leg and chest is in critical condition. A 24-year old man who was shot in the left leg is stable, another 22-year-old man who was shot in the neck and back is critical and a 23-year-old man who was shot in the head is also critical.

A witness told NBC10 he heard nearly a dozen shots fired and one of the victims appeared to be lifeless on the porch of a home on the block.

"All you heard was my aunt scream and when you walked to the door there were three bodies," Chris Griffin told NBC10.

The shooting occurred only a few blocks from where six people were shot during a graduation party last month.

"I still feel a little shaken up especially since that is somebody's loved one and it was kids running out the block and you just decided to go and shoot no matter who was there," Griffin said.

Police have not released a description of any suspects.

Ross said there is a fear of possible retaliation. Investigators would be out in the neighborhood early Monday morning.
