The bombing investigation has focused on a number of terrorist organizations, including the Popular Front for the Liberation of Palestine-General Command. An employee of the security consulting firm hired by lawyers representing Pan American's insurance carriers gave polygraph tests to three Pan American baggage handlers in Frankfurt, Germany. The employees were asked about their knowledge and experience with explosives. Polygraph results are not admissible in court, but polygraph results can be used to provide new leads in the case. The man who administered the polygraph tests in Germany was served a subpoena on his return to the United States, and testified before a federal grand jury last week.
