The Oklahoma Highway Patrol tells KRMG that the suspects fled in an early-90's model, blue Chevrolet Cavalier.

OHP says the suspects should be considered armed and dangerous.

An argument between two groups of men erupted in gunfire late Thursday, leaving one man dead and three agencies investigating to determine what happened.

Glenpool Police Chief Dennis Waller told KRMG at the scene that the confrontation began at the Walmart Super Center, just southwest of W. 121st Street and U.S. 75 in Glenpool shortly before 9:30 p.m.

He says the argument involved two men in one vehicle and three men in another, described as a small, blue car.

The fight moved a few hundred yards south and west, near the Glenpool Conference Center and at that point evidence at the scene indicates that the victim exited the vehicle.

It's unknown at this point in the investigation whether anyone else left their cars.

That's when one of the men from the blue car produced a semi-automatic handgun and opened fire, striking the victim at least once.

Waller says the victim and his friend got back in their vehicle and left the scene, traveling to Barnhart Trailer Court on 141st Street, west of the city limits in Creek County.

Either enroute to the trailer park or shortly after arriving, the gunshot victim died from his wounds.

The other man was not injured.

Waller says they have only sketchy descriptions of the suspects.

He describes them as white males, possibly between 20 and 30 years old.

Waller said the man who was not shot was possibly intoxicated and hasn't been able to provide investigators with much information early in the investigation.

Waller said the Creek County Sheriff's Office was dealing with the scene at the trailer park.

He and his officers were holding the scene near the Conference Center for the Oklahoma State Bureau of Investigation who have been requested to assist in the investigation.

No names have been released.
