PHILADELPHIA (WPVI) -- Shocking video shows multiple people pulling out guns and opening fire during a deadly mass shooting early Monday morning in the Grays Ferry section of Philadelphia.

The Ring camera footage is now part of a police investigation into a gunfight that left three people dead and 10 others injured.

The shooting happened just before 1 a.m. on the 1500 block of South Etting Street.

After making several arrests over the weekend, police were monitoring reports of large gatherings and loud music.

They were in the process of responding to a nearby call when they heard the gunfire.

When they arrived on scene they found a dozen shooting victims ranging in age from 15 to 24.

Additionally, another person was injured while trying to get away from the gunfire. That person was not shot as originally reported.

Police released images of several suspects seen on that Ring video.

The victims who were killed have been identified as Zahir Wylie, 23, of the 1100 block of Marilyn Road; Jason Reese, 19, of the 5400 block of Media Street; and Azir Harris, 24, of the 2400 block of College Avenue.

Philadelphia Police Commissioner Kevin Bethel said it appears the shooters were firing indiscriminately even with children nearby.

"This is coward stuff. You see the size of this block - individuals just shooting randomly into houses, into cars," Bethel said. "I mean, this is coward, wannabe thug stuff."

He said it is "hard to understand" why people engage in this kind of behavior.

"But as we do in all of our investigations, we will get to the root cause and we will bring those individuals to justice," Bethel said.

At least one person with a weapon was taken into custody. Their exact involvement is unknown at the time
