Horror/thriller movie title help?

There was a movie that a college student got a job at I believe at the city morgue as the nightguard. On his first day, he was told to do his "rounds" at a certain time and I remember a radio having some significants. I also think there was a serial murderer (murdering hookers) involved in the storyline... What is the title of this movie?
