It's CDAN's list. The account number used to hide all the dirty deeds of the Cabal.
This gal who died (Kimberly Watzman) knew all the secrets of The Standard Hotel, from working the front desk. She knows who used the account.

But that wasn't the threat. When Ed Buck murdered a male prostitute, Adam Schiff helped him cover it up by having Watzman's helicopter go down.
