I got a response from the CBOE... they forwarded me the text of another article (this one from 2003). I'll post it below...
I was also directed to the SEC website, and found this:

FBI Concludes No Terrorist Insider Trading Occurred in U.S.
Sept. 18 (Bloomberg) -- U.S. criminal investigators have concluded that there was no insider trading in U.S. securities markets by people with advance knowledge of the Sept. 11 terrorist attacks of 2001, an FBI spokesman said.
The Federal Bureau of Investigation found that a pre-attack surge of trading in options that bet on a drop in the stock of AMR Corp., which owns American Airlines, and UAL Corp., which owns United Airlines, was not linked to terrorists, FBI spokesman Paul Bresson said in an e-mail to Bloomberg News.
The two airlines owned the jets that terrorists commandeered and then crashed into the World Trade Center in New York and the Pentagon outside Washington. The FBI investigated possible insider trading on airline and insurance securities in a search for accomplices who might have tried to profit from the attacks.
``The vast majority of trading was conducted by investment hedge funds implementing bearish investment strategies or hedging a line position of common stock,'' the e-mail said. ``No criminal violation or intelligence linking the matter to terrorist activity was identified.''
Bresson didn't identify the hedge funds or any insurance company. Bresson's e-mail came in response to a Bloomberg inquiry
about the status of the investigation.
Numerous Interviews
``We conducted numerous interviews of witnesses and trading professionals,'' Bresson wrote. ``Documents including trading records and SEC data were also recovered and reviewed. These documents detail transactions occurring before and after the 9/11 attack. The investigative efforts did not identify any involvement by terrorists in short selling or trading of put options,'' which let investors bet that a stock will decline.
Bresson said the matter was also ``extensively reviewed'' by the U.S. Attorney's Office in the Southern District of New York and by the U.S. Securities and Exchange Commission.
Lorie Van Auken, the widow of a Cantor Fitzgerald LP bond trader who died in the Sept. 11 attacks, said the FBI told her and other victims' relatives about the conclusion in July. The FBI declined to name the hedge funds when asked by the relatives, Van Auken said in an interview from her home in New Jersey.
``I have a problem with that answer,'' Van Auken said ``If there's nothing to hide, then why can't they tell us?''
Options trading statistics examined by Bloomberg News in the weeks after Sept. 11, 2001, showed a surge of trading in the days before the attacks.
Options Trading
On Sept. 10, 2001, for example, 1,535 contracts changed hands on options that let investors profit if AMR stock fell below $30 per share before the following Oct. 20. That was almost five times the total number of those Oct. 20 put options that traded before Sept. 10, according to Bloomberg data.
AMR closed at $29.70 the day before the terrorist attacks and fell as much as 47 percent to $15.90 when trading resumed on Sept. 17, 2001. UAL, which closed at $30.82 on Sept. 10, 2001, fell as much as 43 percent to $17.50 when U.S. equity markets reopened a week later.
The FBI said in January 2002 that Spanish authorities had uncovered evidence pointing to possible terrorist trading and that the FBI was assisting with that investigation.
Bresson's e-mail didn't answer a question about the status of the Spanish probe and officials at the Spanish Interior Ministry declined to comment.
