NEW HAVEN, Connecticut (AP) — Police released a Yale University animal research technician on Wednesday after collecting DNA samples and questioning him in the killing of a graduate student who worked in the same lab.
Raymond Clark III was taken into custody Tuesday night at his apartment in Middletown, Connecticut, and was released into the custody of his attorney early Wednesday, New Haven police said.
Investigators are hoping to figure out within days whether Clark can be ruled out as the killer.
Clark's attorney, David Dworski, said Wednesday his client is "committed to proceeding appropriately with the authorities." He would not comment further.
Police left the apartment Wednesday morning after searching the scene for hours overnight looking for evidence in the killing of Annie Le.
Clark has been described as a person of interest, not a suspect, in Le's death. Her body was found stuffed behind a wall in the laboratory Sunday, which was to have been her wedding day.
Clark and and his fiancee, Jennifer Hromadka were both animal research technicians in the lab where Le worked.
Hromadka wrote on her MySpace page that she's not perfect, but cautioned people not to judge her.
"Who are you to judge the life I live? I know I'm not perfect and I don't live to be, but before you start pointing fingers make sure your hands are clean!!" the 23-year-old wrote.
The date of the MySpace posting is unclear. The page has since been taken down.
Overnight, state police officers sorted through items on a card table set up outside Clark's ground-floor apartment's door.
A tow truck took away a red Ford Mustang neighbors say was used by Clark.
Police started tearing down the yellow crime scene tape as daylight broke. At that point there had been no sign of Clark's return to his apartment, and neighbors said they hadn't seen Hromadka in the area for days.
Clark's apartment appeared empty Wednesday morning after police left. No one answered the door.
During the search, one officer commented that the apartment smelled like animals. Multiple neighbors said they saw Clark and Hromadka load luggage, cats and two rodents into a vehicle on Saturday.
Falcon said she also saw Clark loading a suitcase and a duffel bag into a car Sunday at about 5 p.m.
New Haven Police Chief James Lewis said police were hoping to compare DNA taken from Clark's hair, fingernails and saliva to more than 150 pieces of evidence collected from the crime scene. That evidence may also be compared at a state lab with DNA samples given voluntarily from other people with access to the crime scene.
"We're going to narrow this down," Lewis said. "We're going to do this as quickly as we can."
Police have collected more than 700 hours of videotape and sifted through computer records documenting who entered what parts of the research building where Le was found dead.
Le worked for a Yale laboratory that conducted experiments on mice, and investigators found her body stuffed in the basement wall of a facility that housed research animals.
On Tuesday, state prosecutors blocked the release of Le's autopsy results, reasoning that they could hinder their investigation. The Connecticut medical examiner had already called the death a homicide but hadn't reported the manner of Le's death.
