Encounter with The Lone Gunmen
In May 1989, Detective Munch investigated the breaking and entering of a warehouse in Fells Point Industrial Park. He interrogated John Fitzgerald Byers and learned of the events that had occurred at the Baltimore Convention Center involving Susanne Modeski, John Fitzgerald Byers, Richard Langly, Melvin Frohike, and FBI Special Agent Fox Mulder. Byers, Langly, and Frohike were arrested for the trespassing, Modeski disappeared, and Agent Mulder was taken into custody by the FBI.
