Inmate killed in altercation at federal prison in Colorado

Officials say an inmate has died following a confrontation with another inmate at a federal prison in Florence, Colorado.

The Pueblo Chieftain reports 37-year-old Maxie Graham was pronounced dead at a hospital following the altercation Sunday morning.

Prison spokesman Marlan Bacon says staff attempted life-saving measures and emergency medical personnel were called to the prison to transport the inmate to a hospital.

Bacon says no staff members or other inmates were injured.

The FBI is investigating the death as a possible homicide. Authorities did not say how Graham died.

Graham was serving a seven-year sentence on drug distribution charges. He had been incarcerated at the Florence prison since February.
