I actually also tend to that theory XDDus wrote: Changed my vote to Anna.
I blame Takagi, pointing out who little the body resembles her ID. Made me think this might be a blatant hint it's NOT Anna.
She is a very capable make-up artist and could easily pull it off. She has also cut her hair recently, in her ID and in the flashback we see her with long hair.
[me=Dus]waits for Chekhov to deconstruct his half-baked theory[/me]
The table was also made by Anna. So just light people can be on it. Meaning it would be most comfortable for females to act this role. Also, both males have a wounded leg, meaning they can't do that shaking effect (bumping the leg stuff)
Problem is if Anna can mimic the voice of Suguri Mutsumi in case she's her now D:
I also wonder why someone would invite Kogoro and then make a murder. Maybe Anna saw a challenge in that?
