Manuel Vincent Martin, 30, suffered a bullet wound in the chest but had no other major visible injuries

Police are searching for a dark-colored car that may have been involved in the shooting death of a motorcyclist on the Glendale (2) Freeway.
An autopsy was performed on the victim Thursday, but the results were not available, authorities said.
Manuel Vincent Martin, 30, suffered a bullet wound in the chest but had no other major visible injuries, according to Los Angeles County Department of Coroner spokesman Craig Harvey.
Police confirmed Thursday that another motorcyclist riding with Martin was wearing a Mongols Motorcycle Club T-shirt. The Mongols, a biker gang that originated in Montebello in the 1970s, has been warring with the Hell's Angels.
Gang involvement is being investigated as a possible motive in the slaying, according to Glendale Police Department Sgt. Tom Lorenz.
Several people showed up to the crime scene following the shooting, Lorenz said.
"The apparel that they were wearing indicated an association with the Mongols," he said. "There was one individual with a Mongol tatoo."
"The Police Department has not ruled out any outlaw biker activity that may have caused this event," he added.
