Theriot was arrested in January after he allegedly went on a killing spree in Ascension and Livingston Parishes, killing five people.

Last month, a grand jury in Ascension Parish indicted Theriot on two counts of first-degree murder for the slaying of his parents, 50-year-old Elizabeth Theriot and 50-year-old Keith Theriot.

He's also indicted for first-degree murder in the killing of his girlfriend, Summer Ernest, as well as her brother and father. Officials said Theriot had been living with Ernest's family for about two weeks before the shooting, after he was kicked out of his parents' home.
