New Haven (WTNH) - The New Haven Register reports police have obtained a DNA match that implicates Raymond Clark III, 24, in the slaying of Yale graduate student Annie Le.
Police have obtained, or are in the process of obtaining, an arrest warrant, the sources said.
Meanwhile, 10 Amistad continues to hold secrets. What exactly happened in the basement of the multi-million dollar Yale research building?
ABC News reports that Raymond Clark texted Le, on the day of her disappearance, that they should meet and talk about the "dirty mice;" potentially referring to the animals she was working on in the lab for research.
ABC News also says following Le's death, Clark had wounds on his back, his chest and arms -- indicating a sign of some sort of struggle -- and was tracked, through his building key card, going into several rooms of the lab.
Still, New Haven Police Chief James Lewis kept fairly mum about the investigation throughout Wednesday evening.
"We're still making sure who was in that building, who had access to the locations in that building...until they are completely eliminated, we're trying to keep track of them, we're doing that pretty successfully," said Chief Lewis.
Still, it seems the New Haven Police Department has its sights set on Clark.
He was taken into custody Tuesday night, and police issued two search warrants, one for his Middletown apartment and the other for his body, where DNA was taken.
He was released around 3:00 a.m. Since then, police executed another two search warrants, for Clark's car and some more property that belonged to the Yale employee. Clark invoked his rights while he was with officers.
"I can never predict what a person might or might not do, I have no authority to detain him in any way at this time," Police Chief Lewis said.
The tipping point for police, and perhaps for Clark, is the DNA. More than 250 items have been seized, and the state lab has been working around the clock analyzing anything and eventually everything that comes their way.
The basis of this investigation is in the physical evidence and they believe there is only one suspect.
Meanwhile, police are stationed in Cromwell, where Clark is staying in the Super 8 motel.
"As far as the role of the Cromwell Police Department, we are a support role with New Haven PD," said Captain Roy Nelson of the Cromwell Police Department. "They are in our town and they are conducting a surveillance and we are there to support them with any needs they may have."
Clark has not been officially charged in the death of Le.
