Jeffery Grey Allen, 34, has been scheduled for trial on a charge of capital murder in the shooting death of 86-year-old, Charles Mason of Helena.
Allen is one of two charged in the slaying of Mason, who owned Mason's Junkyard in East Jackson County. Authorities say Mason was robbed and shot to death at his home on March 2, 2011.
According to authorities, Allen told deputies where to find the rifle used in the incident.
Donna Marie Freeman of St. Martin is also charged with capital murder, but has not yet gone to trial.
Allen will go before the Jackson County Circuit Court Monday.
