The lab technician accused of killing a 24-year-old Yale graduate student tried to hide and clean up evidence of the crime while police were investigating the scene, according to court papers released this morning.
The arrest warrant affidavit for technician Raymond Clark III says police found Clark’s DNA on evidence found with Annie Le’s strangled body and on blood-stained items hidden elsewhere in the lab building where she died September 8.
The arrest warrant affidavit publicly lays out detailed evidence against Clark for the first time. It had been sealed since his arrest on September 17. Connecticut judge Roland Fasano released the document at the request of several news organizations, but blacked out two sections of the document dealing with the discovery of Le’s body on September 13.
Le, a PhD student in pharmacology, disappeared on September 8. The affidavit shows that she used her Yale ID to swipe into a lab building at 10 Amistad Street at 10:09 that morning. At 10:11, she swiped into a secure basement lab area. That was the last time she used her card. Her roommate reported her missing late that night.
The last room that Le swiped into was lab room G-13. When police arrived to investigate there, the affidavit says, Clark let himself into the room and tried to obscure from view a blood-spattered box of wipes that were sitting on a cart. Tests later showed Le’s DNA — obtained from personal items at her apartment — matched the blood spatter on the box of wipes.
Police also found evidence containing “blood-like stains” hidden above a drop ceiling in a hallway outside the lab area: a white sock, work boots, and a scrub shirt. “Video surveillance revealed a similar type shirt worn by Clark,” the affidavit says — and the boots were labeled “Ray-C.” In a recycling box, investigators found a a size-XL lab coat with red-colored stains. Lab tests found a mixture of Clark’s and Le’s DNA on the sock.
Police finally located Le’s body behind a wall in a utility compartment behind a locker room toilet, also in the lab basement. With her body were a sock that matched the one found above the ceiling, and a pen with green ink. A blood stain on the pen contained Le’s DNA, and Clark’s DNA was found elsewhere on the pen.
While police were investigating the scene on September 10, Clark made numerous apparent attempts to throw them off the trail, the affidavit suggests. In addition to trying to hide the bloody box of wipes, he scrubbed areas of the floor that were already clean; changed his clothes at least once; and approached a Yale police officer, saying that he knew Le and that she had left the building in the early afternoon of September 8, the affidavit says.
The arrest warrant affidavit, along with those for two search warrants, were sealed at the request of prosecutors — speaking for Le’s family — and Clark’s defense lawyers. The search warrant documents are scheduled for release on November 17. Clark is being held on $3 million bond and has yet to enter a plea.
