FAIRLAND — The death of a Delaware County man is now being investigated as a suspicious incident, the Oklahoma State Bureau of Investigation confirmed Friday.
Andrew Joel Olsen, 27, of Grove, was found dead Dec. 31 in a tributary of the Neosho River near Grand Lake in the Fairland area by a land surveyor.
The state medical examiner's office reported earlier this week Olsen's autopsy report is pending.
OSBI agents are working to pinpoint his date of death. Investigators have not found anyone who saw Olsen after Nov. 7, the state agency said in a news release.
Those with information related to the investigation are asked to call OSBI at (800) 522-8017.
