According to authorities a body found in a home in Montana is that of a former Sioux Falls resident.

Bismarck Police Lt. Gary Malo told The Bismarck Tribune that a body found on June 26 in a Poplar, Mont. home is that of 18-year-old John Swain. Originally from Sioux Falls, Swain had recently moved to Bismarck, North Dakota.

Swain, 18, was reported missing in mid-May. Police believe two men lured him into a Bismarck home, hit him with a hammer, cut off his legs, cleaned up the crime scene and hid his body.

Two people have been charged in connection with the murder. Joshua James Clark, 20, and Theo Crowe, 25, were charged with conspiracy to commit murder. Swain's body was found at the home of Crowe's grandmother.

According to the Tribune:

The investigation into Swain’s disappearance became a homicide investigation June 20 after a Bismarck woman found the burnt remnants of clothing, a knife and pieces of a cellphone. Investigators determined the clothing matched what Swain was wearing when he was last seen. Crowe had been staying at the woman’s house during May while she was out of state. She reported also finding blood in her home when she returned. Investigators serving search warrants at Crowe’s grandmother’s home in Poplar found a body on June 26. Residents of the town said officers had been digging in the yard.

Police have not released a motive for the murder.
