Annie Le murder investigation

The police made some progress in the case of Annie Le - the Yale student - crime investigation. It seems the Le was strangled and the examiner issued the cause of decease as "traumatic asphyxia due to neck compression". One person - Raymond Clark - was detained by police in order to provide blood samples for DNA tests and he was released afterwards because he agreed the procedure and was cooperative. Clark, a Yale technician answered for a while the police questions but subsequently he got an attorney and stopped. He remains under surveillance like some other suspected persons but at the moment none is arrested or accused. The investigators gathered more than 250 pieces of evidence samples and the searches continue. In the end Raymong Clak is accused of killing Annie Le. Clark's former girlfriend, Jessica Del Rocco revealed that the technician seemed to be a perfect guy in the beginning but later he became possessive and controlling.
