I Dont Even Care That Much Why Seonwoo Was At The Places Where He Found Them - Tumblr Posts

Seonwoo might be the third psychic but def not the killer. My guess is he sees the person's past that last touched the object he touches (which would make his job at the store a great way to find out about everyone). His mother's death is probably also be connected to assemblyman Cha, just like Yebun, which is why he's interested in her. Btw love how we've not touched the drug ring in ages, Cha's probably involved in that too. My guess for the serial killer is Cha's assistant. He's been shown quite a lot.
