Capt. Bo Mathews said a man, whose name has not been released, went into the restaurant and opened fire, wounding two people. After leaving the restaurant, the suspect was confronted by a person who was armed with a gun and opened fire, fatally striking the suspect.

Oklahoma City Lt. Jeff Flaggert said officers responded about 6:30 p.m. to Louie's Grill and Bar, 9401 Lake Hefner Parkway, where the shooting had occurred.

A passerby shot and killed a man who went into a Lake Hefner restaurant Thursday evening and opened fire.

Two people were taken from the scene in emergency status to OU Medical Center, said Lara O’Leary, spokeswoman for Emergency Medical Services Authority.

Mathews said one person fleeing the scene suffered a broken bone in his arm.

The suspected shooter was pronounced dead at the scene.

Ron Benton, 54, of Oklahoma City, was at the bar in Louie's when he heard gunfire coming from the front doors. He said he didn't see anyone shot, but he went outside with others who rushed out the doors.
