FULLERTON (KTLA) -- Police are hoping images caught on a surveillance camera can help identify the person responsible for beating man into a coma at a Fullerton gas station.

The attack happened on June 5, but Larry Markin is still in a medically induced coma. Every bone in his face is broken, his brain is swelling and doctors fear he may not survive.

Surveillance video shows a suspect in a Dodge Durango pulling into a Chevron gas station on the corner of Euclid Street and Orangethorpe Avenue, his body language signaling that he may already be outraged. He then walks to the back of the building where he grabs Markin out of his vehicle, hits him three times in the face before jumping on him and beating him.

Police were alerted of the incident by a tow-truck driver who saw the late night beating. "The best we can put together... is that some sort of traffic dispute or road rage dispute that lead to the fight," Fullerton Police Sgt. Andrew Goodrich said.

Witnesses said the beating lasted about 8 seconds.

"I saw him open the truck, open the door, and pull [Markin] out," witness Dayna Lord told KTLA.

Markin, 56, is a grandfather and proud father of two servicemen. Family members said he was returning home from a bachelor party when he was attacked at the gas station less than a block from his home.

He is currently undergoing treatment at UC Irvine Medical Center in Orange.

The suspects vehicle is described as a light colored Dodge Durango SUV. Witnesses describe the suspect as a Hispanic male, 5-feet 8-inches tall with short hair.

Anyone with more information is asked to call Fullerton Police at (714) 738-6800.
