NEW HAVEN, Conn. -- A Yale official says a lab technician accused of strangling a graduate student had access to campus buildings until he was arrested more than a week after the woman disappeared.
Yale spokesman Tom Conroy says the card that allowed Raymond Clark to enter Yale buildings was not deactivated until early Thursday.
He is charged with murdering 24-year-old graduate student Annie Le, originally of Placerville, Calif., on Sept. 8.
Clark was under constant surveillance even before Le's body was discovered in the lab building five days later. Conroy wouldn't say whether Clark continued to work in the days before he was arrested.
Yale suspended Clark after his arrest.
