PHILADELPHIA (CBS) — Philadelphia police have released surveillance video of four suspects allegedly involved in a deadly beating outside Pat’s Steaks in South Philadelphia. The attack happened early Thursday morning at 9th Street and Passyunk Avenue.

Video of this incident is graphic and hard to watch. Police are hoping by releasing it, this will bring those suspects to light.

That’s when officers say two groups got into a physical altercation that turned deadly.

In the video, you see one of the suspects holding a metal trash can lid before hurling it.

Investigators say 28-year-old Isidro Cortes died as a result of those blows, while his 64-year-old father and a 28-year-old friend were seriously injured.

“He was taken from us too soon, he was so young,” Tania Tepale, the victim’s cousin, said.

Philadelphia police released the nearly 5-minute video in hopes of bringing her family justice by finding the four suspects.

“It’s sad and like in a place where there are a lot of people and people are having fun. It’s weird to see something so tragic happen,” Pat’s customer Margaret Fabacher said.

Police say after the fight, the suspects drove off in two vehicles — one identifiable by damage to the right rear panel, the other a truck with a sunroof.

They’re also asking the public to look at the suspects’ distinct tattoos and soccer jerseys.

Cortes’ family says he was an accountant from Queens, New york. He was only here to see a soccer game.

A $20,000 reward is being offered for information leading to an arrest and conviction for every homicide.

“There are a lot of people and people are having fun,” Margaret Fabacher, a Pat’s Steaks customer, said. “It’s weird to see something so tragic happen.”
