Nicholas Ely was one of three people convicted of first-degree murder last year and sentenced to life for the July 2011 death of Kris Winters.
Winters was killed after a botched robbery attempt at his home. Ely was one of four men who sent a teen girl in to Winters’ home to pose as a marijuana customer before the robbery.
Ely argues in his appeal that there was not enough evidence to convict him and that his trial judge gave a faulty jury instruction and wrongly admitted some evidence.
The high court will hear arguments in the case on Sept. 3.
