Criminal Law:

Murder- First-degree

In the majority of states, first-degree murder is defined as an unlawful killing that is both willful and premeditated.  this means that it was committed after planning or "lying in wait" for the victim, and not "in the heat of the moment."

Most states further hold to a legal concept known as the "felony murder rule," under which a person commits first-degree murder if any death, even an accidental one, results from the commission of certain violent felonies, usually arson, burglary, kidnapping, rape, and robbery.
