Lab Tech Arrested in Annie Le Slaying

After days of suspicion, police arrested Raymond Clark III today in the killing of 24-year-old Yale University graduate student Annie Le. He was taken into custody at a hotel where he was staying in Cromwell, Conn., about about 25 miles north of New Haven, and his bond is set for $3 million. Le's body was found Sunday stuffed in a basement  wall of the lab building where they both worked.

Le vanished from the Yale Medical School building on Sept. 8, just days before she was to marry her college sweetheart. The investigation has centered on Clark, 24, a Yale animal research technician. Authorities served Clark, 24, four search warrants this week and were comparing DNA taken from his hair, fingernails and saliva with more than 250 pieces of evidence collected at the crime scene.
