NEW YORK (AP)—A former nightclub bouncer convicted of brutally murdering a graduate student from Boston was sentenced Wednesday to life in prison without parole.

Darryl Littlejohn was convicted of first-degree murder last month for the 2006 killing of criminal justice student Imette St. Guillen, 24.

Littlejohn, 44, already is serving 25 years to life for kidnapping another woman. The sentences will run consecutively.

St. Guillen, capping a night out, went to a Manhattan bar called The Falls early on Feb. 24, 2006.

She stayed at the bar past closing. Witnesses said she was asked to leave, and Littlejohn escorted her out.

At sentencing, State Supreme Court Justice Abraham Gerges criticized the bar workers. “If one of them had the common decency to call a taxi, we might not be here today,” he said.

St. Guillen’s body was found later that day wrapped in a quilt along a desolate road in Brooklyn. She was bound and gagged, and she had been beaten and sexually assaulted before being asphyxiated.
