Another tenant explains that she went to a convenience store after putting some clothes to wash in the machine. He observed this because it was emitting a different, loud noise. He also tells that there was a 5-minute pause in between. Conan, through a sleeping Sonoko, deduces that the employee is the murderer. She took the ticket but the aprons between them got exchanged.
