December 31, 2013, a land surveyor discovered a body in a tributary of the Neosho River near highway 60 east of Fairland. The medical examiner’s office identified the man as Andrew Joel Olsen (d.o.b. 5-21-1986) of Grove. At this point, Oklahoma State Bureau of Investigation agents are investigating his death as suspicious. Agents are working to pinpoint his date of death. So far, investigators have not found anyone who saw Olsen after November 7, 2013. OSBI is asking anyone who saw or spoke with Olsen after November 7th to please come forward. Weather conditions at the time Olsen’s body was discovered have made it difficult for the medical examiner to provide a date of death. If anyone has information to help with this investigation, please call the OSBI hotline at 1-800-522-8017.
