An inmate serving his first year of a life sentence for murder has died in custody in Cameron, Mo.

67-year-old Joseph Arbeiter was admitted into the Missouri Department of Correction on Dec. 18, 2014.

He was serving a  life without parole sentence for first-degree murder, armed criminal action, first-degree sodomy or attempted sodomy, first-degree rape or attempted rape, first-degree sexual abuse, unlawful use of a weapon, second-degree assault, and possession of controlled substance from Clay County.

According to the Sedalia Democrat, Arbeiter pleaded guilty in the murder of Mandy Black in Dec. and to an attack on a neighbor in a Sedalia area trailer park.  The news agency reported the sentences came days after the 51st anniversary of his first murder charge in St. Louis when he was accused of the murder of 28-year-old Nancy Zanone, a married mother of two children during a burglary in 1963 and sentenced to life without parole.  His first sentence however, was overturned by the Supreme Court in Oct. 1966 and sent back to court because officers failed to take him directly to the juvenile court as the law required.

Arbeiter was pronounced dead at 9:54 p.m. Saturday at Crossroads Correctional Center in Cameron of apparent natural causes.
