"Sources tell 60 Minutes that the initial options were bought through at least two brokerage firms including NFS, a subsidiary of Fidelity Brokerage, and TD Waterhouse, a discount firm.
TD Waterhouse says they handled approximately 3 percent of the initial orders for "puts" on American Airline stock. The company says it has looked at the orders and has determined no evidence of any suspicious activity."

"The source familiar with the United trades identified Deutsche Banc Alex. Brown, the American investment banking arm of German giant Deutsche Bank, as the investment bank used to purchase at least some of the options. Rohini Pragasam, a bank spokeswoman, declined comment."

This one is more specific but it looks like it is directly off MCR's Oct 9/01 report almost a week prior:
"Further details of the futures trades that netted such huge gains in the wake of the hijackings have been disclosed. To the embarrassment of investigators, it has also emerged that the firm used to buy many of the "put" options where a trader, in effect, bets on a share price fall on United Airlines stock was headed until 1998 by "Buzzy" Krongard, now executive director of the CIA.
Until 1997, Mr Krongard was chairman of Alex Brown Inc, America's oldest investment banking firm. Alex Brown was acquired by Bankers Trust, which in turn was bought by Deutsche Bank. His last post before resigning to take his senior role in the CIA was to head Bankers Trust Alex Brown's private client business, dealing with the accounts and investments of wealthy customers around the world."

Nothing conclusive on who the 95% investor was. The "FBI Briefing on Trading" MFR goes on and on about market pessimism. Mentions nothing about banks,traders etc. Now those answers were destroyed by the SEC a while ago.
