Convicted rapist and murderer Deaneric Dupas will get a second chance to argue for a lesser prison sentence for his role in the 1997 slaying of New Milford teen Maryann Measles.

The lawyer for Mr. Dupas, 33, is set to go Nov. 24 before a three-judge Sentence Review Panel and argue Mr. Dupas didn't get credit for helping prosecutors in their case against co-defendant Keith Foster.

Mr. Dupas' lawyer, David Moraghan, declined comment Wednesday.

Mr. Dupas was sentenced to 47 years in prison in January 2005 on rape and murder charges.

He and six other people were convicted in the October 1997 killing of Maryann, 13, who was kidnapped, raped and strangled before being wrapped in a blanket and chains and dumped into the Housatonic River in New Milford.

Maryann was killed after filing a complaint with police alleging two of the defendants had sexually assaulted her, authorities said.
