RENO, Nev. (AP) – A former cook shot and killed a former co-worker as the two had a snack at a sleepy casino in downtown Reno, Nevada, authorities said Monday.

Suspect Kiley Grayson, 38, stayed at the scene and was arrested on suspicion of murder, police said. It’s unclear if he has an attorney.

The shooting occurred at Siri’s Casino just before midnight Sunday. The identity of the man who died at a hospital hasn’t been released.

Casino owner Jeff Siri said the two men had been cooks at a nearby sister property, although neither was on the job during the confrontation.

Grayson is a former employee who stopped coming to work a few days ago, he said.

Siri said he was told by witnesses that the men were eating at a snack bar toward the back of the casino with at least one other person, who was walking away as the shooting happened.

“The employee that got shot pushed (the shooter) with his cane, and that’s when he pulled the gun out, within seconds. It was really fast,” Siri said.

Police spokesman Officer Timothy Broadway said he could not immediately confirm the account provided by Siri.

Siri said the small casino has 96 slot machines and no table games. There were about 10 customers and two employees working at the time. No one else was hurt, he said.

“We’re broken up about this thing. I know he had some young children,” Siri said of his employee who died. “It’s terrible to see something like this, especially someone whose got a lot of people to take care of.”

The casino was closed during the investigation but has since reopened.

Siri said the casino doesn’t have signs posted but has a policy prohibiting firearms.
