UPPER MARLBORO, Md. (CBSDC/AP) — A Maryland man who shot an off-duty state trooper who kicked him out of a restaurant was ordered Thursday to spend the rest of his life behind bars by a judge who called him a threat to society.

Cyril Cornelius Williams, who maintains his innocence in the June 2010 murder of Trooper Wesley Brown, made no apologies to the trooper’s family as he was sentenced to life without parole plus 25 years.

“Your vengeful acts deprived our community of a young public servant and of a crusader for the at-risk youth of this county,” Prince George’s County Circuit Court Judge Sean Wallace said in imposing the maximum possible sentence.

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

An irate Williams drove away to pick up a gun from a friend, returned to the restaurant and shot Brown multiple times.

Anthony Milton, the man who provided the gun used to kill a Maryland state trooper outside the restaurant was sentenced was sentenced to 5 years in prison in February. Milton was 29 years old at the time of the sentencing.
