New Haven police released Yale lab tech Raymond Clark III early Wednesday morning after holding him for a few hours overnight as a “person of interest” in the killing of graduate student Annie Le. Though he’s not considered a suspect, Clark was apprehended Tuesday night so that DNA samples could be taken from his hair, skin, and saliva. Le’s body was found Sunday in the lab where Clark worked. Le was set to marry on Sunday; Clark currently lives with his fiancée. ''They didn't strike me as someone who would try to kill somebody,” said a neighbor, who described the couple as “really quiet.” Clark’s car was also towed away.
