I completely agree. [There's a short pause as he takes a breath.]

Each murder scene seems like a different part of the body. Part of remains is on display or meant to be drawn attention to.

...it also seems like the displays are getting bolder. Or I guess, more upfront. I don't have enough evidence to guess if the killer is watching us collect the corpse or not. But it seems like they had to have had something set up in advance for the blood.
