Apparently in example sentence
He hides the body in some hatch on the roof and afterward something snaps inside of him and he moves beyond the stage of repression and voyeurism to full blown murder, as well as necrophilia (which is handled with some subtlety here); apparently the only way he can 'get off.' Might explain why he's been paying a local hooker (played by 70s drive-in favorite Roberta Collins) to dress up like his long gone momma and "play dead" while he undresses and gropes her.
