The Nebraska Supreme Court has upheld the sentence of a man convicted of helping former Nebraska football player Thunder Collins in a fatal shooting.
Karnell Burton is serving 80-to-130 years for manslaughter, attempted murder and other charges in the September 2008 shooting death of Timothy Thomas.
Burton had asked the state's high court to throw out his conviction because, among other things, a district judge wouldn't let his attorney present evidence that two state witnesses were gang members.
The state's high court said Friday that there was no merit to Burton's arguments.
Earlier this summer, the high court gave Collins a shot at a new trial when it found a lower court had erred by allowing the jury to break for a weekend before delivering its guilty verdict.
