A former animal research technician faces sentencing for killing a Yale University graduate student days before her wedding.

Twenty-six-year-old Raymond Clark III is scheduled to be sentenced Friday in New Haven Superior Court.

Clark pleaded guilty to murder in March to attempted sexual assault of 24-year-old Annie Le of Placerville, Calif., under an agreement with prosecutors that calls for a 44-year sentence. The plea was entered under Connecticut's Alford doctrine, where the defendant doesn't agree to the facts, but agrees the state has enough evidence to get a conviction.

Le's body was found stuffed behind a lab wall on Sept. 13, 2009, five days after she was last seen inside the Yale medical building. It would have been her wedding day.

Le's mother and Clark's relatives are expected to speak.
