Raymond Clark III, an animal lab technician at Yale University, was arrested earlier today for the murder of Annie Le, reports the New York Times. His bail has been set at $3 million. New Haven police say he had been a "person of interest" since Monday because of bruises and scratch marks on his chest and arms and that DNA evidence later obtained also connected him to the case. Yesterday afternoon Connecticut's chief medical examiner released that the cause of Le's death was strangulation.
