The victim was Jerry Bigwall, the owner of The Livingstone Club, and a friend of Mayor Johnson. He was found face down in a cake, with a river of blood flowing down from his mouth. The killer turned out to be Mitchell Westville, the Westville heir.
To arrest Mitchell, David Jones disguised himself as Jerry and approached Mitchell at the Garden Party by surprise. Mitchell said that he killed Jerry because Jerry got him drunk one night, thus making him reveal that his family was broke, while Jerry recorded him saying that. Mitchell did not want his family name to get spoiled as the people in Maple Heights would have regarded him with disdain if they had known the truth, and he said that murder was a lesser crime in this district. Mitchell wanted to administer Jerry the truth serum because he wanted access to Jerry's safe in the Livingstone Club, but he failed as Jerry would tell the truth behind the Westvilles anyway. To preserve the Westville name, Mitchell opted to kill Jerry by rigging a cake with razor blades. Jones then revealed his true self to allow the player to make the arrest.
In court, Mitchell told Judge Hall that the families of Maple Heights existed for centuries, and had been the most respected people of Grimsborough, but Judge Hall countered that all Mitchell did was add murder to the Westville name. In spite of Mitchell's words, the court deduced that a murder, no matter the details of and the motives behind the occurrence, was a punishable offense even though the slaying was justified which were grounds for a lifetime jail sentence for Mitchell.
