Thirty eight year old Beau Musial of Richfield appeared in a Washington Court room on Monday to face charges of murdering his father in their family home in December 2013. Judge Andrew Gonring ruled that Musial was not guilty by reason of mental disease or defect and committed him for life to the Department of Human Services. In January, Judge Gonring ruled Musial committed the crime. At a hearing in April, Judge Gonring found Musial not guilty by reason of mental disease or defect in the brutal slaying. According to the criminal report, On December 21, 2012, Musial called 911 and admitted to killing his 76-year-old father. He told a detective that he and his father, Jerome Musial argued about a tractor trailer and that he had become so angry that he punched his father in the face several times until he became unconscious. Musial then went to the kitchen of the home he shared with his father and returned with a knife and cut his father’s throat using a sawing motion several times. Judge Gonring also ruled that once Musial is committed he can petition for conditional release or early termination of commitment.
