The Yale University animal research technician who police say is a "person of interest" in the death of graduate student Annie Le has been released, the Associated Press reports.
According to the AP:
A police department spokesman, Officer Joe Avery, says Raymond Clark left the station with his lawyer at about 3 a.m. Wednesday.
Clark has not been charged in the killing of 24-year-old Le, whose body was found stuffed behind a wall Sunday in a Yale laboratory building where both she and Clark worked. Police are calling him a "person of interest."
The wire service adds that police collected DNA samples from Clark and have searched his apartment.
Update at 1:30 p.m. ET: The Connecticut state medical examiner says Le died of "traumatic asphyxiation," the AP reports.
