A northwestern Pennsylvania prison inmate has been charged in the stabbing death of another inmate earlier this month.
Twenty-five-year-old Trevon Coleman is charged in Erie County with criminal homicide, aggravated assault, possessing instruments of crime and other counts.
State police allege that he stabbed 33-year-old Job Knighton of Erie on Feb. 10 with a homemade weapon at the State Correctional Institution at Albion.
Police allege that the suspect then "body-slammed the victim headfirst into a concrete floor and stomped on his face."
The Erie Times-News reports that court documents indicate that Knighton was serving a 34- to 70-year sentence in a rape case while Coleman is serving a three- to seven-year robbery term.
Court documents don't indicate whether Coleman has an attorney who could offer comment on the charges.
