A 27-year-old man who fatally shot his cousin while the two were re-enacting a gun scene from a movie has been sentenced to five to eight years in prison. Erasmo Castillo of Baytown, Texas, was sentenced in Lander on Thursday for the death of Cesar Perez Jr. He previously pleaded guilty to involuntary manslaughter. Castillo says he didn't realize the gun was loaded when he pulled the trigger at a motel in Riverton on Aug. 12th. He and his cousin had just arrived in town from Texas to work. Castillo apologized in court for the shooting, saying "I wish I could take it back, but I can't."
