A man whose naked body was found on a golf course in northwest Minnesota is believed to have died from hypothermia.

The Forum News Services reports that 35-year-old Andrew Jon Springer was declared dead at the scene after he was found at the Sandhill River Golf Course near the city of Fertile at around 4 p.m. Monday.

The Polk County Sheriff's Office said in a news release that Springer's body was taken to the University of North Dakota's forensic pathology laboratory for an autopsy, and that no signs of foul play have been found.

Valley News Live also reported that authorities initially said he appears to have died from exposure which led to hypothermia.

Deputy Sheriff Brian Lundeen told the Star Tribune that Springer had recently moved to Fertile from Washington state, and lived less than two blocks from the course’s eastern edge.

The Mail Online reports that he is the father to an infant daughter.
