Police Say No More Arrests Planned in Yale Killing After Confiscating Car Owned by Suspect's Father

Police do not expect to make more arrests in the killing of a Yale graduate student in her lab building, police said Monday, two days after they confiscated a car owned by the suspect's father.

New Haven Police Chief James Lewis discounted media reports that police were considering whether suspect Raymond Clark III, 24, had an accomplice in the killing of Annie Le, also 24.

"It's still my belief I don't expect anyone to be charged," Lewis said. "But I don't know where the evidence may take us. No arrests are expected at this point."

Lewis confirmed that a car towed by police Saturday from the Cromwell, Conn., hotel where Clark was arrested belonged to his father, Raymond Clark Jr. He wouldn't say why police obtained a search warrant for the car.

An attorney for the younger Clark didn't return a call Monday.

Le, originally of Placerville, Calif., was strangled Sept. 8 and her body hidden in a wall recess in a Yale medical school research building. Her body was found five days later on what was to be her wedding day.

Clark was arrested Thursday, a day after he was ordered to give hair, fingernail and saliva samples to compare with evidence from where Le's body was found.

Clark was an animal lab technician, cleaning floors and mouse cages in the lab where Le conducted research. Her team experimented on mice as part of research into enzymes that could have implications for treatment of cancer, diabetes and muscular dystrophy.

A law enforcement official has told the AP on condition of anonymity that co-workers called Clark a "control freak" who was territorial about the mice whose cages he cleaned. Police are investigating whether that attitude might have set off a clash between Clark and Le.

Le will be remembered Wednesday at a private memorial service at the temple that her fiance's family attends, said Rich Pilatsky, whose wife is the cantor at Temple Beth El in Huntington, N.Y.

Le's funeral is being handled by the Green Valley Mortuary in Rescue, Calif.
