Felony Murder During Robbery Rape
Sebastian Santos and an accomplice rob a convenience store. During the robbery Sebastian forces the clerk into a back room and commits sexual intercourse by force. The clerk dies from injuries sustained in the struggle. The prosecution relies on the presumption that the killing occurred under circumstances manifesting extreme indifference to human life because Sebastian was engaged in rape during the robbery.
Common Law Rape Elements
Sabrina Shah, not married to Skylar Sullivan, has carnal knowledge of Skylar without her effective consent. The act satisfies the penetration requirement even though no emission occurs. At common law the conduct constitutes rape because the man is not the woman's husband and the intercourse occurs without effective consent.

Common questions
Frequently Asked
4
What constitutes penetration for purposes of sexual intercourse under the Model Penal Code?+
The Model Penal Code defines sexual intercourse to include intercourse per os or per anum with some penetration however slight. Emission is not required. This definition applies to both rape and deviate sexual intercourse offenses.
Supporting sources
How does common law rape differ from Model Penal Code rape regarding the victim's gender and marital status?+
Common law rape requires a man who is not the woman's husband to have carnal knowledge of a woman without her effective consent. The Model Penal Code retains the requirement that the victim be a female not the actor's wife but expands the means by which consent can be rendered ineffective, including through force, threats, intoxicants, unconsciousness, or age under ten.
Supporting sources
When does impairment of capacity for sexual intercourse give rise to a tort claim by a spouse?+
A spouse may recover for loss of society and services, including impairment of capacity for sexual intercourse, when the other spouse suffers bodily harm from a third party's tortious conduct. The claim must ordinarily be joined with the injured spouse's action for bodily harm.
Supporting sources
Does discovery of a spouse engaged in sexual intercourse constitute adequate provocation at common law?+
Yes. Catching one's spouse in the act of sexual intercourse with another person is a classic category of adequate provocation that can reduce an intentional killing from murder to voluntary manslaughter if the other elements of heat of passion are satisfied.
