The OSBI says 39-year-old Duane Preciado died after being shot Wednesday night in the Tulsa suburb of Owasso.
The OSBI says Preciado carried an AK-47 as he met two officers responding to a disturbance call about 10:30 p.m., and was shot as he moved toward officers while making threatening comments.
About eight hours earlier in Mannford, about 20 miles (32 kilometers) west of Tulsa, 47-year-old Mark Allen Lunn was shot by officers investigating a report of a suspicious man in a neighborhood.
The OSBI says Lunn was walking away from officers when he pulled a knife from his pants and was shot when he moved toward the officers.
