Mulder to tell them the truth as he understood it. He explained that the entire alien and UFO conspiracy was nothing more than an elaborate series of lies to draw attention away from sinister military experiments on an unsuspecting public. So-called "abductions" were actually careful military tests involving chemical and biological warfare, among other things. Kritschgau's son died as a result of Gulf War Syndrome, which he fell party to because of his work at the Defense Advanced Research Projects Agency and connections to a pharmaceutical company called Roush. Following the incidents, Kritschgau was fired. In 1999, the discovery of an alien spacecraft off the coast of Africa caused Mulder to begin experiencing intense mental trauma. While in the hospital, Mulder requested that Skinner bring in Kritschgau, who would know what to do. Kritschgau recognized Mulder's symptoms from his work in the CIA and was able to identify the correct drug to slow down Mulder's brain activity to a normal level. He then became involved in the investigation of the spacecraft symbols, having hacked into Scully's computer and downloading the images she took. Kritschgau's involvement was soon noticed. Alex Krycek was sent to steal his files and burn his apartment, but only after he shot Kritschgau dead. The name for this character came from Gillian Anderson's real-life friend from growing up in Grand Rapids, Michigan. Richard Matheson Senator Richard Matheson, portrayed by Raymond J. Barry, was a politician that took a liking to Fox Mulder and was interested in his work at the FBI. After the X-Files were shut down in 1994, Matheson prompted Mulder to visit the Arecibo observatory in Puerto Rico to continue his search for the truth. Eventually, Matheson distanced himself from Mulder because he felt his political career might be in jeopardy. Later that year, Mulder went to Matheson's office in an attempt to contact him to gain information about Scully's abduction, but he was intercepted by X, who told him that Matheson could not give him the information he wanted without risking himself. He later gave Mulder a lead that led him to government program to import Japanese scientists to the US after World War II. Mulder ran into Matheson years later while investigating a mysterious illness contracted by Walter Skinner. Matheson was directly involved in an illicit deal concerning nanotechnology. The incident further soured relations between Mulder and Matheson. Billy Miles Billy Miles, portrayed
