Lock up your horses
Wisconsin man guilty of dead deer sex.
In addition to the whole, "sex with roadkill" thing, there's also this tidbit.
"Hathaway was found guilty in April 2005 of felony mistreatment of an animal after he killed a horse with the intention of having sex with it. He was sentenced to 18 months in jail and two years of extended supervision on that charge as well as six years of probation for taking and driving a vehicle without the owner’s consent. "
