PORTLAND (AP) — A man who was serving seven life prison sentences for killing two men in Maine and abducting his estranged wife in 1999 has committed suicide in a federal prison in Georgia.

A county coroner in Georgia tells the Portland Press Herald that 50-year-old Steven Brown hanged himself at the medium-security prison in Jesup on May 29.

Brown pleaded guilty in 1999 to all federal and state charges against him in the case, including murder, kidnapping, interstate domestic violence, interstate stalking and firearms offenses. He had asked the judge to sentence him to death, but the judge refused. Brown had previously tried to kill himself in prison but failed.

Brown’s case stemmed from an abusive relationship with his former wife that exploded into violence that took two men’s lives.
