I've managed to identify 9 (or 10) out of 12 investigators and I'm not sure about the last two. Anyone cares to enlighten me on the last two?
My source is the official video at 5:16
These are identified:
-Trish Scarborough (I'm not sure about her, she is right behind Leo)
The remaining two are left of Lily Chen (I suspect Finn Edwards) and left of Jim Culver (Jacqueline Fine?).
