Did Nancy Kerrigan's Brother Kill Their Father Daniel Kerrigan?

As though she didn't experience enough suffering at the hands of Tonya Harding's hired thugs, now it looks as though Nancy Kerrigan's brother may have killed their father. Mark Kerrigan allegedly assaulted his father early Sunday morning, potentially causing injuries that led to Daniel Kerrigan's death hours later. The younger Kerrigan reportedly thought his father was "faking" when he fell down. The police report says Mark Kerrigan acted belligerent and appeared intoxicated when officers arrived on the scene. The cause of death has not yet been determined and no charges have been filed. The case is still under investigation. Update: Mark Kerrigan has been charged with assault and battery with a dangerous weapon. [Boston Globe]
