I don't think that was the protagonist.

[Spoiler below if anyone hasn't seen it]

There was guy setup in a room who was pretending to be a pedo so that the protagonist would kill him and his family would get paid by the antagonist.

The protagonist chooses not to kill him which also proves that it wasn't certain anyone else convicted by their psychic tech would have killed.

IIRC the person was being framed as a serial kidnapper/killer to explain a bunch of missing children, with no specific extra motive.

Anyway, here's a video clip of the fictional cops looking at the suspiciously full room of evidence:
