Sam decided to kill his boss, Anna, after she told him that he would be fired if his work did not improve. Sam knew Anna was scheduled to go on a business trip on Monday morning. On Sunday morning, Sam went to the company parking garage and put a bomb in the company car that Anna usually drove. The bomb was wired to go off when the car engine started. Sam then left town. At 5 a.m. Monday, Sam, after driving all night, was overcome with remorse and had a change of heart. He called the security officer on duty at the company and told him about the bomb. The security officer said he would take care of the matter. An hour later, the officer put a note on Anna's desk telling her of the message. He then looked at the car but could not see any signs of a bomb. He printed a sign saying "DO NOT USE THIS CAR," put it on the windshield, and went to call the police. Before the police arrived, Lois, a company vice president, got into the car and started the engine. The bomb went off, killing her. The jurisdiction defines murder in the first degree as any homicide committed with premeditation and deliberation or any murder in the commission of a common-law felony. Second-degree murder is defined as all other murder at common law. Manslaughter is defined by the common law. Sam is guilty of 
murder in the first degree, because, with premeditation and deliberation, he killed whoever would start the car.  murder in the second degree, because he had no intention of killing Lois.  manslaughter, because at the time of the explosion, he had no intent to kill, and the death of Lois was in part the fault of the security officer.  only attempted murder of Anna, because the death of Lois was the result of the security officer's negligence.
