Officials have identified a correctional officer who died after a brief altercation that also killed an inmate at a Pennsylvania prison.

Luzerne County Coroner William Lisman on Tuesday identified the officer as 25-year-old Kristopher Moules of Larksville.

Moules was killed Monday night at Luzerne County Correctional Facility in Wilkes-Barre (WILKS'-ba-ree). Officials previously identified the inmate as 27-year-old Timothy D. Gilliam Jr.

Lisman says both men died of multiple traumatic injuries from a fall. The inmate's death was ruled accidental. Lisman is not yet ruling on the officer's death, pending further investigation.

Officials aren't yet saying what led to the altercation or how exactly the two men died.
