NEW HAVEN, Conn. (AP) - Yale University President Richard Levin says he's confident about the safety of the New Haven campus, but more precautions are being taken after a homicide last month.
Levin's comments came in an e-mail sent to faculty and staff this week. He says improvements are being made to emergency communications in isolated indoor and underground areas.
Graduate student Annie Le was killed Sept. 8 in the basement of a Yale laboratory building with restricted access. A lab worker, Raymond Clark III, is charged with murder.
Levin did not mention retired Yale employee John Petrini, who was arrested without incident last month when he brought a rifle to campus while upset about his benefits.
Levin also says temporary employees will now undergo background checks.
