CHEYENNE, Wyo. (AP) - A lawyer says a Sheridan man serving life without parole in the January 2010 stabbing death of another man deserves a new trial. The Wyoming Supreme Court on Thursday heard arguments in the appeal of Shawn Osborne. He was convicted of first-degree murder in the death of 42-year-old Gerald Bloom.
Lawyer David Westling of the Wyoming Public Defender's Office told the court Osborne had been drinking heavily and taking amphetamines before Bloom was killed. Westling argued Osborne's trial lawyer should have called an expert witness to testify about the combined effect of the alcohol and drugs on Osborne's ability to make a decision to kill Bloom. Kyle A. Ridgeway with the Wyoming Attorney General's Office argued that Osborne's trial lawyer did an adequate job and that Osborne's conviction should stand.
