In March 2009, Robert Stewart opened fire in a nursing home in Carthage, N.C., killing eight people and wounding two more.
His defense team argued that he was under the influence of the sleeping pill Ambien, and not in control of his actions, at the time of the shooting. Stewart faced trial last year and was found guilty of eight counts of second-degree murder. He was sentenced to 142 to 179 1/2 years in prison.
