A wrestling coach was sentenced Thursday for sexually assaulting a 14-year-old female wrestler. Fifty-six-year-old Keith T. Matsumoto was sentenced to six months in jail for third-degree sexual assault for molesting the girl during the 2012 Aloha State Games wrestling tournament at Farrington High School. A state jury found the longtime wrestling coach and coordinator of the state high school wrestling championships guilty in February. He faced a maximum five-year prison term.
