Problem:
Alma believed that Ed, her employer, had cheated her out of overtime pay. She asked her friend, Bob, a locksmith, to open a locked drawer in Ed's desk so that she could obtain confidential documents for use in embarrassing Ed into paying her what she thought he owed her. Bob said he would help her. Alma took Bob to Ed's office, where he opened the locked desk drawer. Just after Alma and Bob had removed the confidential documents from the drawer, Ed came into the office. Startled, he chased Bob onto a balcony and pushed him. Bob fell over the balcony railing and landed on Diane, who was walking on the sidewalk below. Bob was unharmed but Diane died instantly.
