NEW HAVEN - A warrant released Friday shows that DNA linked to the murder of a Yale graduate student matches that of lab technician Raymond Clark III.

DNA evidence was traced from a bloody sock and a pen discovered at the Yale medical building, according to the document. Annie Le's body was found behind a wall in the building on the day she was to be married in September.

Clark has not yet entered a plea but his attorney says he will plead not guilty.
