The Nebraska Supreme Court rejected the appeal Friday by an Omaha man convicted of second-degree murder in a 2010 shooting at an auto shop.
Shawn McGuire was sentenced to 105-to-125 years in prison for murder and two other convictions. Authorities say McGuire was the getaway driver in the slaying of 36-year-old Cesar Sanchez-Gonzalez, a government drug informant.
In his appeal, McGuire alleged several errors by the trial court. Among them, he said the trial judge should not have accepted McGuire's waiver of conflict of interest after his former lawyer began working for the prosecutor's office.
The high court disagreed in its ruling, saying there is no evidence to show the district court's decision to accept the waiver was erroneous.
