Police took into custody Raymond Clark 3rd on Tuesday, a person of interest but not a suspect in the killing of Yale graduate student Annie Le.

Clark is 24 years old, good looking and reportedly lived with his fiancée in Middletown, Conn. He worked as a lab technician and was there the morning that Le was last seen. Clark was released on Wednesday morning after police collected DNA. Officials also searched his home.

Annie Le disappeared on September 8. Her body was found on September 13 stuffed inside a wall of a medical research building's basement. The day she was supposed to marry.

Details surfaced about Le's autopsy on Tuesday, showing she was asphyxiated before her body was stuffed into the wall, the New York Post reported. Tiny drops of blood revealed she was killed in one room in the basement lab and then moved to another room where she was crammed.
