HAMILTON, OHIO: The last of four men has pleaded guilty in the shooting death of a teen during a botched drug robbery attempt in Southwest Ohio.

West Chester police say 18-year-old Tyler Kassow died after being shot in January.

Police say two men with ski masks forced their way into the home and scuffled with Kassow, who was shot once in the head. Two other men were waiting in a car nearby.

Twenty-year-old Jibril Willingham pleaded guilty on Monday to aggravated robbery. His defense attorney, David Washington, says Willingham never went into the home.

Twenty-year-old Demarcus Staley pleaded guilty last week and was sentenced to 21 years to life in prison.

Rodney Foster and Justin Koch, both 19, previously pleaded guilty and were sentenced to 15 years to life.
