Teen pleads guilty to second-degree murderNov 1, 2013 The Associated Press
GREEN RIVER -- A Rock Springs teen has pleaded guilty to second-degree murder in the 2012 death of a 17-year-old boy.
Nineteen-year-old Brady Jacob Trevino pleaded guilty Wednesday before state District Court Judge Nena James as part of a plea agreement.
Authorities say Rigoberto "Junior" Alvarado, of Rock Springs, died on July 29, 2012, or June 30, 2012, and his body was found on Aug. 19, 2012, by a group exploring the remains of abandoned coal camps and mining operations north of Rock Springs.
Trevino said he and Alvarado got into a fight and he hit Alvarado with a baseball bat and put a plastic bag over his head.
A pre-sentence investigation will be done. No sentencing date was set.
