ATTICA, Ind. — Indiana Conservation Officers are asking for the public’s help to find a missing man who they say has exhibited suicidal tendencies.

Jason Allen Underwood, 37, was reported missing on April 25. Officers say he is presumed to be on a boat on the Wabash River.

Officers say Underwood’s vehicle and boat trailer were discovered at the Attica boat ramp on the Wabash River. His boat is described to be a 15 foot 1979 Smoker-Craft. The registration number displayed on the boat is IN1111BH.

Officers have been actively searching the Wabash River by boat and foot since Underwood was reported missing. They’ve searched the Wabash River from the SR234 Bridge to the Granville boat ramp. The Vermillion River was also searched in its entirety, extending to the Illinois State line.

If you have any information pertaining to this case, please call ICO’s Central Dispatch at (812) 837-9536. If a boat matching the description or a person matching the photo is located, officers ask that you do not approach for your own safety, it is unknown whether Underwood is mentally stable.
