LIVINGSTON — A 21st Judicial District Court judge sentenced a Walker man to 20 years in prison on a drug conviction and probation violation, the District Attorney’s Office reported Friday.

Dean Coutee, 45, of Percy Young Road, Walker, was sentenced to 10 years after pleading guilty to operation of an illegal methamphetamine laboratory, according to a news release from District Attorney Scott Perrilloux.

District Judge Ray Chutz sentenced Coutee to 10 years on that charge subsequent to sentencing him to two five-year terms after revoking his probation on earlier cases of possession of methamphetamine and theft of more than $1,500, prosecutor Greg Murphy said in the news release.

The sentences are to be served consecutively, Perrilloux said in the release.

Coutee was on probation when he was attested in August after a search of his home by the Livingston Parish Sheriff’s Office revealed a small methamphetamine operation, according to the release.
