Pennsylvania law defines third-degree murder as a murder which is neither a first-degree murder ("criminal homicide... committed by an intentional killing") nor a second-degree murder ("committed while defendant was engaged as a principal or an accomplice in the perpetration of a felony"). For purposes of that section, "felony" is specifically defined as "engaging in or being an accomplice in the commission of, or an attempt to commit, or flight after committing, or attempting to commit robbery, rape, or deviate sexual intercourse by force or threat of force, arson, burglary or kidnapping." There are also parallel crimes of first-degree, second-degree, and third-degree murder of an unborn child. There does not exist the crime of third-degree murder of a law-enforcement officer, only first-degree and second-degree. Third-degree murder and third-degree murder of an unborn child are punishable by a maximum of 40 years' imprisonment.
