An inmate at California State Prison, Sacramento in Folsom has been sentenced to 28 years to life in prison for assaulting a fellow inmate.
Steven Thompson, 51, was convicted last month by a Sacramento County jury of assault on another inmate, personally inflicting great bodily injury and possession of a weapon, according to a Sacramento County District Attorney's Office news release.
Thompson is serving time in prison for first-degree murder and attempted murder. In 1981, he shot at two unarmed high school students from his car after an altercation, authorities said. Both victims were hit and one died at the scene. Before he was apprehended, Thompson plotted to kill the other victim so he would not be able to identify Thompson.
While in prison, Thompson stabbed another inmate on the prison yard with an inmate-manufactured knife, authorities said. The victim suffered a punctured lung as a result of the assault.
