MARIANA — Florida authorities say an inmate who killed his cellmate last month while awaiting trial for killing another cellmate in 2015 is now in solitary confinement.
TheNews Herald reports 21-year-old Frederick Patterson III said he killed his 82-year-old cellmate Arthur Williams on Jan. 15, and told correctional officers that "there's one less child molester on the streets."
Patterson, a convicted burglar, was sentenced Thursday to life in prison for killing 45-year-old Scott Collinsworth, a convicted robber, in the Apalachee Correctional Institution.
Patterson now faces a first-degree murder charge. Williams, who was accused of trying to lure a 9-year-old boy into his car, had been ruled incompetent 10 days earlier and was being held in the Jackson County Correctional Facility awaiting transfer to a mental facility.
The News Herald reported that Marianna Police Department reports said, "officers arrived about 2 a.m. Jan. 15 to find Williams face-down in the men's shared cell in a large puddle of blood. Williams was pronounced dead at the scene from 'catastrophic blunt force trauma to his face,' officers wrote."
Patterson told investigators he and Williams had been cellmates in maximum security for about two weeks, and he had planned to kill Williams the entire time.
