Who Killed Ben on "Only Murders in the Building?" The Season Finale Cracked the Case

Mabel is actually not involved at all with "Death Rattle," and Oliver and Charles both note that they've all been spending way less time together. She has a long-standing crush on Ben, dated to the days when he starred on "Girl Cop." It's not clear how much she and Ben interacted before his death, but she has no motive for the murders. Plus, like Charles and Oliver, she was in the elevator when he died.

Our verdict: Not guilty
