(CNN) -- A lab technician charged in the strangling of a Yale graduate student less than a week before she was to be married plans to plead guilty Thursday, his attorney said.
Raymond Clark III will plead guilty at a court in New Haven, Connecticut, as part of a plea bargain, according to public defender Joseph Lopez.
Lopez would not divulge the details of the agreement.
The 26-year-old had pleaded not guilty in January 2010.
He is accused in the killing of Annie Le, 24, who was pursuing a doctorate in pharmacology at Yale when she went missing on September 8, 2009.
