Florida authorities say an inmate who killed his cellmate last month is now in solitary confinement.
Frederick Patterson III, 21, 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 also sentenced Thursday to life in prison for killing another cellmate in 2015, 45-year-old Scott Collinsworth, in the Apalachee Correctional Institution.
Patterson now faces a first-degree murder charge.
Williams, who allegedly tried 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.
