CLEVELAND (AP) - An 18-year-old recognized as the top prep football player in the state pleaded guilty Tuesday for his role in the shooting death of a teammate.

Raymond Williams faces three to 20 years in prison at his sentencing Nov. 16 on involuntary manslaughter and aggravated robbery charges.

Williams, a running back at Benedictine High School, was named the 17th annual winner of The Ohio Associated Press Mr. Football award last November.

Police said Williams, Jon Huddleston and Lorenzo Hunter, all members of the school's state-champion football team, allegedly tried to use a toy gun April 16 to rob Rodney Roberts, who pulled a gun and began shooting.

Hunter, 16, died of gunshot wounds to the chest, arm and hip.

A grand jury ruled that Roberts, 20, shot in self-defense. He was sentenced earlier this year to probation for carrying a concealed weapon.

Williams was initially charged with murder.
