NEW HAVEN, CT (AP) - New Haven police say they have released a Yale University animal research technician they questioned in the killing of a graduate student after collecting DNA samples from him and searching his apartment.
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 Annie 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."
Police took Clark into custody Tuesday night at his apartment in Middletown.
