That’s "Psycho." An on-duty Los Angeles County sheriff’s deputy allegedly had sex with a woman near the Bates Motel section of the Universal Studios lot — and accidentally left his microphone on for a dispatcher to hear a blow-by-blow of the sleazy romp. TMZ obtained a clip of the X-rated encounter between the unnamed deputy and a woman near the section of the lot in Universal City devoted to the Alfred Hitchcock classic.
