GROVE, Okla. — Authorities say a 28-year-old man has died after he reportedly stabbed two people then set himself on fire in a lakefront area of northeast Oklahoma.

The Oklahoma State Bureau of Investigation says the three men were co-workers and had stopped to eat lunch Thursday at Monkey Island on Grand Lake, about 70 miles northeast of Tulsa.

Authorities say an altercation occurred, and the man stabbed his co-workers.

Grand Lake Regional Airport manager Paul Staten tells the Miami News-Record that the suspect then poured gasoline on the ground and lit it on fire before rolling around in the flames.

The OSBI says the suspect, Joseph Honaker of Tulsa, died early Friday from his injuries. Authorities say the other two men were treated and released from hospitals.
