Sergeant Lockwood and Detective Doyle reread all statements and reports regarding Marilyn's murder and present 14 facts and corresponding contentions/analysis and a synopsis. They surmised that Sam's affair with Susan Hayes could have been a motive for killing Marilyn, or at least a cause of the argument during which he lost his temper and killed her. They also proposed that Sam went down to the lake to wash off the blood on his clothing and staged a burglary after he had killed Marilyn.
