University of Michigan hires law firm Jenner & Block and expands an independent review of athletics culture and procedures after interim president Domenico Grasso announced a probe following the firing and arrest of football coach Sherrone Moore.Prosecutors say Moore was arrested hours after his termination for allegedly forcing his way into a former staff member's home, threatening to kill himself and making death threats; the Washtenaw County Sheriff's Office released his mugshot and he was freed on a $25,000 bond with a GPS monitor and a mid-January court return.
