CHEYENNE, Wyo. (AP) — The Wyoming Supreme Court has upheld a sentence of life in prison for a Cheyenne man found guilty of killing two people and wounding a third at his home five years ago.

The court on Tuesday rejected arguments from Nathaniel Castellanos that the state violated his right to a speedy trial. The court also rejected Castellanos' claims that his trial lawyers did an inadequate job and that there were errors in selecting jurors.

Castellanos was convicted in 2013 of two counts of murder and one count of attempted murder in the August 2011 shootings.

Police found Corey Walker and Megan McIntosh dead at Castellanos' home. Another woman, Amber McGuire, survived gunshot wounds and testified against Castellanos at trial.

Cheyenne lawyer Elizabeth Lance represented Castellanos on appeal. She declined comment Tuesday.
