TULSA, Oklahoma - A fight turned deadly at Shotgun's Bar early Sunday morning, Tulsa police said.

Sgt. Chris Maudy told News On 6 that bar patrons at the bar, 39th Street and Garnett Road, got into an argument at about 1 a.m.

"It spilled out in the parking lot and gunfire erupted," Maudy said.

By Sunday night, homicide detective Dave Walker released a statement saying the shooting was the result of a "chance meeting" between rival Asian gangs.

Jone Vang and another man pulled guns and fired upon each other, according to Sgt. Dave Walker. Vang, 21, was shot several times and died of his wounds.

A short time later, another man was dropped off at St. Francis Hospital with injuries from a shooting, and police determined he was linked to the altercation at Shogun's, according to Walker.

The investigation is focused on the people who dropped the wounded man off and then fled the hospital.

Multiple shell casings were found in the bar's parking lot, but no weapons were recovered.

Walker said the gang unit's assistance helped detectives track down several witnesses, and police believe they have identified those involved.

"The integrity of the investigation prevents us from revealing the names of those we are searching for that have knowledge of this case," Walker said.

Walker said Vang has been described as an active member of an Asian street gang.

Vang is the city's 40th homicide of 2013.
