The body of 34-year-old mother of four Susan “Susie” Casey was found in the Yellowstone River in 2008. The three men in her life were investigated. There was her husband Ted Casey, with whom she was headed toward divorce. There was Brad Holzer, who she was dating. (He dropped her home in the early morning, just hours before her death.) And then there was her jealous ex-husband, Walter “Marty” Larson, Jr., who watched Holzer drop off Susie, with her bra slung over her arm. After a four-year investigation, Larson was found guilty in 2013 of murdering Susie. She was strangled with “considerable force” before being placed in the river.
While serving a 110-year sentence in prison, Larson appealed his conviction arguing that “he didn’t waive his Miranda rights and asked for an attorney during a February 2012 interrogation.” However, the Montana Supreme Court upheld his conviction. It was a 5-0 decision. The justices wrote in a ruling: “We do not find it necessary to wade into the murky waters of this interview and determine whether Larson invoked his right to counsel or right to remain silent.”
