Investigation at Yale Continues

DNA and hair samples were taken from a "person of interest" in the Annie Le homicide case, according to a New Haven police spokesperson. The New York Times reports that Raymond Clark III has been the focus of the investigation since Monday and was released from police custody early this morning after providing the samples. Clark is an animal lab technician in the same Yale facility where Le was found. Clark was held for about five hours before his release. The Times adds that Le made no complaints about being harassed or stalked in the time leading up to her death.
