.
if everyone alive is accounted, maybe someone dead was alive at some point.
dont know if this is what u are missing, hope it helps
also is easy to check the timelines using "find" and the identificator of the person
i got 98 files, there is a hint in File: 21-CH-3
about 10-MA-5-6 , do you have the entire timeline of everybody? seems like u are missing one scene
you got everyone in the mansion.
read carefully @
this game is amazing
