Only Murders in the Building: The Biggest Suspects For Tim's Murder, From Least to Most Likely

Something about Howard just feels off to us, almost like he's hiding a big secret. It also doesn't help that his cat's paw prints were all over the murder scene. However, out of all the suspects so far, he definitely seems the most harmless.

It's hard to believe that Mabel would be digging into a murder she committed — plus the private video she records in episode two pretty much confirms she's not Tim's killer — but why would she go to such great lengths to keep their friendship a secret? Does she know more than she's letting on about Tim's death and Zoe's murder all those years ago?

Right now, the most mysterious suspect on the show is the "tie-dye guy," who has yet to be identified. As far as true crime stories go, that alone makes him one of the biggest suspects. After all, he was spotted going up the staircase to the roof the night of Tim's murder. Although, the flash-forward in the first episode does show Mabel kneeling over a presumably dead person wearing a tie-dye hoodie. If he's Tim's killer, who has it out for him?

As we learn more about the Hardy Boys in episode two, it becomes apparent that Tim's death is part of a bigger mystery. It might even be connected to Zoe's death that occurred 10 years earlier. If that's the case, then there's a good chance that Tim's killer and Zoe's killer could be one in the same.
