Raymond Clark, a 24-year-old technician who worked in the lab where murdered Yale student Annie Le studied, was arrested as a "person of interest" in the investigation last night. After the New Haven police department retrieved DNA from him, he was released. Police have been following Clark since Monday, but he is not an official suspect, and Le had not complained in the weeks before her death of any harassment from him. According to police, Clark will either be charged or exonerated in the next few days. [NYT]
