Life-sentence appeal denied

The Wyoming Supreme Court published a decision denying a convicted Cheyenne murderer his appeal on Jan. 26.

Nathaniel Castellanos appealed his three consecutive life-without-parole sentences for two counts of first-degree murder and one count of first-degree attempted murder, arguing his right to a speedy trial and the Wyoming Rules of Criminal Procedure were both violated because the trial took place more than 900 days after his arrest. He also argued that his attorneys were ineffective since they were not qualified to represent a defendant facing the death penalty.

The Supreme Court heard oral argument about the appeal in mid-October. His sentences were affirmed.

The killings took place in August 2011 at his house. Cory Walker and Megan McIntosh were killed, and Amber McGuire was severely injured. All three victims were Laramie County Community College students. He was found guilty in February of 2014, but the jury rejected the death penalty. Castellanos was sentenced in March of 2014.
