Lab Technician Arrested in Slaying of Yale Student Annie Le
A Yale University lab technician was arrested Thursday and charged with the suffocation death of a graduate student whose body was found stuffed in a research building wall on what was to be her wedding day.

New Haven police said they arrested 24-year-old Raymond Clark III at the the Super 8 hotel in Cromwell, about 25 miles north of the Ivy League campus. Clark had been staying at the hotel since he was released early Wednesday by police, who had served search warrants looking for evidence linking him to Annie Le's death.

New Haven Police Chief James Lewis said there are no other suspects. Authorities would not comment and a possible motive, other than to call it workplace violence. The arrest warrant was sealed by a judge.

"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," Lewis said.

Le, 24, was found dead on Sunday, her body stuffed in the basement wall of a campus research building where she worked, just days before she was to marry her college sweetheart, Columbia University graduate student Jonathan Widawsky. The Connecticut state medical examiner said Wednesday that Le died of "traumatic asphyxiation."

Authorities released no details on how she died, but traumatic asphyxiation could be consistent with a choke hold or some other form of pressure-induced asphyxiation caused by a hand or an object, such as a pipe.

The investigation has centered on Clark, the only person publicly named by New Haven police in the case. Authorities served four search warrants this week to compare DNA taken from his hair, fingernails and saliva with more than 250 pieces of evidence collected at the crime scene on the Ivy League campus and from Clark's Middletown, Conn., apartment.

Clark's attorney, David Dworski, did not immediately return calls seeking comment on Thursday. He has previously said Clark is "committed to proceeding appropriately" with police.
