NORWALK - The New Haven Superior Court released search warrant affidavits Wednesday, revealing new details about the murder investigation of Yale graduate student Annie Le.

The unsealed documents reveal what police say they discovered prior to the arrest of Raymond Clark III. According to the warrant, police found blood stains on the floor of Clark's apartment, but it does not disclose whose blood it was.

The affidavits also contain information about the search of Clark's cars and numerous lockers in the university laboratory where Le was found.

An attorney for Clark's fiancée, Jennifer Hramadka, says authorities are also seeking a sample of Hramadka's DNA, though she is not considered a suspect.

Clark was charged with murder days after the search, but he has not yet entered a plea.
