Authorities have identified the "person of interest" in the killing of Yale graduate student Annie Le as 24-year-old lab technician Raymond Clark III: Police Have 'Person of Interest' in Yale Killing.
New Haven police have apparently been focusing on Clark since at least Monday, and have him in custody but are not yet calling him a suspect. They have a warrant to take samples of his hair, saliva and fingernails for DNA testing to compare to about 150 items taken from the crime scene.
Investigators have also interviewed 150 people and watched 700 hours of surveillance video from the cameras in and around the building where Annie Le's body was found -- and where Raymond Clark worked.
Because there is limited access to the research laboratory, investigators were able to determine who was in the building when Le disappeared. FBI agents interviewed anyone who had access to the lab and gave many of them polygraph tests. Clark had apparently failed at least one polygraph test.
Police said Clark would be released after they obtained evidence from him and his apartment. More here, including a lot more previously unreleased details about the murder case: Lab technician in custody in Annie Le slaying.
