Third-degree rape is a criminal offense that involves engaging in sexual intercourse under circumstances that do not meet the criteria for first or second-degree rape. These circumstances may include lack of consent from the victim or the threat of substantial unlawful harm to the victims property. The specifics of third-degree rape can vary by state, but it generally involves situations where the victim did not consent to the sexual intercourse or where there is a threat of substantial harm to the victims property. Third-degree rape is typically classified as a felony, with penalties that may include imprisonment for a specified period of time, such as up to 25 years in some states.
