(AP) - A Massachusetts man has pleaded guilty to reduced charges of manslaughter and conspiracy to commit murder in the slaying of Greenwich developer Andrew Kissel.

On the eve of his trial, Leonard Trujillo, 23, of Worcester, agreed to the plea deal Friday after prosecutors dropped the murder charge against him under the condition he would testify against his cousin Carlos Trujillo if needed during an upcoming trial.

Leonard Trujillo is expected to be sentenced to 20 years in prison following the trial of his cousin.

Carlos Trujillo, 48, of Bridgeport, is charged with conspiracy to commit murder.

Kissel was found stabbed to death at his Greenwich home in April 2006.
