DENHAM SPRINGS - Prosecutors say they'll be seeking the death penalty for confessed multi-parish killer Dakota Theriot.

On Monday, District Attorney Scott Perrilloux in Livingston Parish said he would pursue the death penalty for the 21-year-old accused of killing five people earlier this year. Theriot pleaded not guilty in court Monday morning.

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

On Monday, he was indicted by a grand jury in Ascension Parish on two counts of first-murder for the slaying of his parents, 50-year-old Elizabeth Theriot and 50-year-old Keith Theriot.

He is being held without bond for his five murder charges.
