Where did she get the staff from when she murdered the third guy? She didn't have it with her when she entered the house, so where did it come from? Also, why did she close the bathroom door and fire three shots? If she was trying to make it look like the same killer, why deviate from the MO?
shareMissed that about the staff. I wondered about the bathroom door ... seems to me the guy could have side-stepped into the bathtub to avoid the shots. Seemed he just stood behind the door. She didn't shoot that quickly. I thought there might have been time for him to try to survive.
But another really amazing question is .. why would she have taken the staff tip to the police in the first place? It was like she was trying to solve her own crime for them ... or, I guess, she was trying to set it up so there would be a fall guy for it and she'd get off scott free. That must have been it.
Yes, I believve she provided the broken off tip first to allay any potential suspicion that might come HER way since she provided evidence; and then to set up the guy as the fall guy.
She was not only clearing away her torturers, she simultaneously was making sure the final guy came off as the guilty guy who hung himself.

She might have had the staff tucked down her pant leg or something (because she can't let the guy see it until she's in the house).
As for the bathroom door, I figured that was part of framing Adam. She's making it look like the victim got away locked himself in the bathroom and was shot through the locked door, then wrote the name "Adam" in blood to identify the killer. She needs a way for the victim to "identify" Adam, which he obviously couldn't do if he were shot in the head and killed instantly.
I think that was the idea, though to me it seems messy (like, I doubt a killer would shoot someone through a door and then leave without making sure he was dead).
In any event, the staging of the third murder was to give a huge hint pointing at Adam. I think this murder is less planned out because she only decides to stage it that way at the last minute. Originally she was just going to kill all four and leave it looking like a serial killer who never gets caught.
