Authorities in Connecticut identified a laboratory technician as "person of interest" in the killing of Annie Le, a 24-year-old graduate student whose body was found behind a basement wall in a medical research building at Yale University, a law enforcement official said on Tuesday.
Chief James Lewis of the New Haven police said the technician, Raymond Clark III, 24, was in custody, but Lewis did not call him a suspect. He said the police had a warrant to take samples of Clark's hair, saliva and fingernails for DNA testing.
"If he cooperates and gives us the evidence, he will be released," Lewis said at a news conference at police headquarters in New Haven on Tuesday night.He said Clark would either be arrested or exonerated by the end of this week.
Lewis said investigators had taken about 150 items from the crime scene with potential DNA evidence they could compare. He also said they had interviewed 150 people and watched 700 hours of surveillance video from the cameras in and around the building where Le's body was found - and where Clark also worked.
Clark had been a focus for investigators at least since Monday, when unmarked police cars pulled up to the apartment complex in Middletown, Conn., where he lives.
He was not there. Neighbors said that on Sunday afternoon, around the time Le's body was discovered, he left with his fiancee, who is also a technician at the Yale lab. The neighbors said they got into a Ford Taurus that drove away. It was not clear when he returned - no one answered the door in midafternoon. But the police picked him up there around 10 p.m. on Tuesday, a week after Le disappeared and two days after she was to have been married on Long Island.
Officials appeared to be moving cautiously with the investigation on Tuesday. For much of the day, they declined to say officially if anyone was considered a suspect. And when Lewis appeared at the news conference, he said that investigators were still looking at other people who had access to the building, near the Yale Medical School.
"We are making sure there are not any other suspects, making sure we don't have tunnel vision," Lewis said.
