The mother of a young sailor killed in a brutal attack in 1992 told the Post and Courier today that he was targeted because he had seen, his superior, having sex with another male sailor.

Investigators told Rosaline Horton that her son, a 22-year-old sailor aboard the minesweeper Exultant, discovered his superior, Thomas Solheim, having sex with another male sailor. She said for the last 17 years investigators have been working under the theory that her son’s death was connected to the discovery.

Naval Criminal Investigative Service agents are not talking about the case publicly but Horton said several crewmembers on board started talking to investigators as soon as her son’s body was found bound and shot in a ditch near Summerville.
