[[John Di Giorgio]] was a former Austrian citizen who was allegedly an undercover informant working against [[Ben Kalka]] for the [[California Attorney General's Office]]. His criminal indictment was filed under seal by the INS on October 26, 1989, and remained secret for nearly a decade. At a news conference on November 17, 1989, former [[California Attorney General's Office|California State Attorney General]] [[John Van de Kamp]] touted the case as the "biggest methamphetamine seizure in the world," displaying 1,022 pounds of methamphetamine and $1 million in cash.[^1]
[[Pam MacLean]], a reporter for the *San Francisco Daily Journal*, spent thousands of dollars to get the Di Giorgio file unsealed. The unsealed documents revealed that the [[United States|U.S. government]] was looking for an alleged $13 million in laundered drug funds believed to be in [[Switzerland]], [[Germany]], and [[Israel]]. The methamphetamine precursors supplied to [[Ben Kalka]] were reportedly part of a "reverse sting" operation headed by [[Federal Bureau of Investigation|FBI]] agent [[Robert Barnes]].[^1]
The federal case number on the sealed indictment is recorded in a federal docket index: No. 3:89-cr-00603 in the [[United States District Court for the Northern District of California|Northern District of California]], filed October 26, 1989 and terminated June 17, 1993. The index lists the parties as the United States and Ben Kalka.[^2] Seymour cites the same number as the "Di Giorgio Extradition File, Case No. CR89-0603 VRW, U.S. verses Di Giorgio."[^3]
