It looks like you are missing the murder ending. If I recall correctly, you need to successfully break into the office without having Marie freed and without Lexy or Zero. EDIT: Confirmed that Frenni must not be freed. You need high Security to pick the lock.

Can confirm, just get the 350 paranormal before the time you can buy things then max out security and buy the thunder ritual (also just in case buy out the military arsenal instead of the charm for Lexy), its the same shade of Red model employee and on the same lines, which indicated that it was a bad ending like all other on that line. ALSO SERIOUSLY IS THAT SOUL BIND TAG SERIOUSLY A RED HERRING?!
