A Maryland man who killed the off-duty state trooper who kicked him out of a restaurant has been sentenced to life in prison without parole.

Cyril Cornelius Williams maintains his innocence in the June 2010 murder of Trooper Wesley Brown. He made no apologies to the trooper's family when he was sentenced Thursday.

Prince George's County Circuit Judge Sean Wallace called Williams a threat to society who deprived the community of a young public servant who helped at-risk youth.

Williams was convicted of first-degree murder for shooting Brown outside an Applebee's restaurant in Forestville in suburban Washington. Brown was working as security when he and his partner threw Williams out of the restaurant for being disruptive, including urinating on a fellow patron.
