Police have re-implicated Yale lab technician Raymond Clark, previously called a “person of interest,” in the murder of Yale University graduate student Annie Le.

Clark was taken into custody Tuesday, but released after he volunteered a DNA sample.

According to The New Haven Register, police have now obtained a DNA match that implicates Clark in the strangling death of the student, who was supposed to get married last Sunday.

Clark is holed up in a motel in Cromwell, Conn., and police have told the Register that he could be arrested at any time and charged in Le’s death.

ABC News has reported that Clark text messaged Le on the day of her disappearance. ABC News also said that Clark had wounds on his back, his chest and arms after Le’s death.

A Yale University lab technician, who works in the building that graduate student Annie Le was found murdered, has been released from custody after the alleged “person of interest” was cleared by a DNA test, according to The New Haven Register.

Raymond Clark, 24, of Middletown, Conn. was taken into custody by police Tuesday. Officers searched his home also.

But DNA appears to have cleared Clark from wrongdoing.

The question remains, now, who murdered the tiny, helpless grad student who was supposed to have gotten married last Sunday?

Connecticut state police have found a body inside the wall of a Yale University building. While police have not confirmed it, presumably this is the remains of missing graduate student Annie Le, who was supposed to be celebrating her wedding day Sunday.

Police have now switched from a missing person investigation to a homicide case, said New Haven Assistant Police Chief Peter Reichard, in a press conference Sunday night.

“Detectives and investigators have a large amount of physical evidence on the scene that we’re going through to determine if it’s linked to this case or not,” Reichard said.

Bloody clothing was found above ceiling tiles in the same Yale building on Saturday, according to reports.

Le, 24, was last seen at the 10 Amistad St. building this past Tuesday. Her family has been notified about the finding of a body, Reichard said.

“Our hearts go out to Annie Le’s family, fiancƒ© and friends, who must suffer the additional ordeal of waiting for the body to be identified,” said Yale President Richard Levin, in a statement to the Yale community. “I have met again with her family and conveyed to them the deeply felt support of the Yale community.”

WTNH-TV New Haven reported that bloody clothing has been found above ceiling tiles in a Yale University building where missing graduate student Annie Le was last seen.

The sources told WTNH News Channel 8 reporter Erin Cox the area where the items were found is now considered a crime scene, but New Haven police officials would only say that “no body has been found.”

Le has not been seen since sometime on Tuesday.

The grad student was supposed to get married on Sunday, but the family has canceled the ceremony.

The local newspaper, The New Haven Register, reported that police are about to brief reporters on the situation.

Anyone with information pertaining to Le’s disappearance is asked to call the FBI tip line at 877-503-1950.

Police at Yale University have issued a missing person’s report on 24-year-old Pharmacology student Annie Le. Le, according to police, left her purse, money and credit cards, her cell phone and all of her identification behind before vanishing earlier this week.

Le was last seen wearing “a knee length brown skirt, bright green short sleeved T-shirt, brown shoes and a brown necklace” the New Haven Register reports. She was last seen outside Yale’s School of Medicine on 10 Amistad St., this past Tuesday.

Le has no medical conditions that could explain her absence, and apparently has no access to a vehicle. She is 4-foot-11 inches tall and of Asian descent with brown eyes and straight shoulder-length brown hair, weighing about 90 pounds.

CNN reports Le was scheduled to be married Sunday to Columbia University grad student Jonathan Widawsky. Widawsky has not heard from his fiancƒ©e. Le’s family is assisting Yale, Connecticut and New Haven police, as well as the FBI, with the case.

Anyone with any information is urged to contact the Yale Police Department at 203-432-4400.
