Lab Technician Charged With Murder of Yale Student

Before there was blood, the high-technology lab at 10 Amistad St. at Yale University was a model of efficiency. The mice and rats and rabbits stayed locked in cages. The technicians responsible for their well-being circulated like emergency room nurses. Researchers hunched over the cages for hours, intent on claiming a breakthrough.

The two groups interacted in professional if perfunctory ways, but on Thursday, the authorities charged a technician, Raymond Clark III, with murdering one of the graduate researchers, Annie Le. Le, 24, was strangled on Sept. 8, and her body was found on Sunday hidden behind a wall, out of view from the immaculate corridors of the laboratory.

Clarke, 24, was arrested just after 8 a.m. Thursday in Room 214 of the Super 8 Motel in Cromwell, Conn. He had been staying there with his father, at the end of several days in which the authorities interviewed him, followed him, took DNA samples and then kept him under surveillance. He was charged with murder and driven back to New Haven, Conn., where he was arraigned but said little and did not enter a plea. Bail was set at $3 million.

The authorities said his DNA matched crime scene evidence, but did not elaborate.

Chief James Lewis of the New Haven police would not speak about a possible motive, but said: “It is important to note that this is not about urban crime, university crime, domestic crime, but an issue of workplace violence, which is becoming a growing concern around the country.”

The chief sought to dispel any notion that Le, who was about to be married, had been stalked by Clark or that Yale itself was unsafe. But the arrest opened a window into a peculiar work environment, populated by thousands of animals, driven researchers and the technicians who perform the laboratory’s menial but essential work.

Those technicians are given a special order: to serve as advocates for the animals and guardians of regulation about how they should be treated.

“There is a certain stress that builds with the job,” said David Russell, who worked as an animal technician at Yale from 1997 to 2008. “If there’s something wrong, you are the one who is on the hook.”

They come from a variety of backgrounds: former veterinary technicians; laid-off workers from pharmaceutical companies; men and women fresh out of high school and college and looking for a decent-paying job.
