An inmate at a federal prison in West Virginia was sentenced to more than 15 years in prison for the death of another inmate last year. Stephen C. Crawford was sentenced to 188 months after he was found guilty by a jury of voluntary manslaughter, assault with a dangerous weapon and assault resulting in serious bodily harm, according to a news release from the U.S. Attorney’s Office for the Northern District of West Virginia. Investigators said Crawford used a handmade weapon to stab another inmate multiple times while he was incarcerated at United States Penitentiary Hazelton in Preston County. The inmate later died of his injuries. Crawford will also serve three years of supervised release following his prison sentence.
