Disney/Patrick Harbron Only Murders in the Building solved Sazz's death only to go ahead and kill off our favorite Arconia doorman Lester - so what does that mean for season 5? The fourth finale, which concluded in October 2024, had Mabel (Selena Gomez), Oliver (Martin Short) and Charles (Steve Martin) trying to track down what led to Sazz's (Jane Lynch) murder. They were able to figure out how her stunt prodigy, Marshall (Jin Ha), stole Sazz's script and killed her to keep it quiet, but there wasn't much time for them to celebrate the solve.
