AUBURN — The body of 35-year-old Ryan-Eric Richardson was found Thursday in the Little Androscoggin River, police said Thursday night.

Police did not release any cause of death. An autopsy was expected to get underway Friday.

Police had searched several areas, including the Little Androscoggin River.

The Maine Warden Service assisted the Auburn Fire Department in recovering the body Thursday afternoon.

Richardson’s cousin, Courtney Gelineau, told the Sun Journal earlier in the week that Richardson had been at a nearby party spending time with friends when a surveillance camera caught him suddenly running across the road toward Don’s No Preference Towing before going into the woods.

The disappearance had been frequently reported on social media in recent weeks, with more and more people getting involved with the search.

Police did not say if foul play was suspected.
