Authorities say a man who was hit and killed by a semi Monday afternoon in Council Bluffs may have committed suicide. Fifty-two-year-old James Hoss, of Watertown, South Dakota, died at the scene of the accident on Interstate 80 eastbound, near the Manawa exit.

According to Council Bluffs police, Hoss was walking on the interstate when was struck by a semi being driven by 37-year-old Sedrick Taylor, of Crestview, Florida. The accident happened at around 1:10 p.m. Officials say while the incident remains under investigation, alcohol and speed were not believed to be factors in the collision.

Instead, they’re looking into the possibility Hoss may have intentionally walked into the path of the semi.
