"KE has been yammering the Stern Crime Team line that the fax was "stolen in a burglary". But I've never believed that. I believe that Kapoor gave it to Roger Friedman."
Or, Ford Shelley could have gotten the original fax sheet and given it to Roger Freidman who confronted Kapoor.
Fax sheets with fax numbers on them are the recipient's copies not the sender's copies.
What would Kapoor's recipient document be doing in the Horizen house? It would be in Kapoor's office.
