Arizona prison inmate charged in 2006 homicide

Posted: Updated:

PHOENIX (AP) -- Authorities say an Arizona prison inmate serving time for an aggravated assault has been charged in a homicide case.

Phoenix police said Friday that Joseph I. Sesmas, 27, has been charged with second-degree murder in the 2006 killing of Stephanie M. Trotter.

A Maricopa County employee found the 27-year-old woman's body in a waste water canal area on Sept. 11, 2006.

Trotter was identified by fingerprints a week later. Investigators say she died from blunt force trauma to the head.

Police say Sesmas was later found driving the victim's reported stolen vehicle, but denied knowing Trotter. Police didn't have enough evidence at the time to make an arrest.

Cold case investigators began looking at the case again, resulting in Sesmas' indictment in May. It's unclear whether Sesmas has a lawyer.
