Theodore L. Gunderson was an American Federal Bureau of Investigation Special Agent In Charge and head of the Los Angeles FBI. He exposed and campaigned against what he believed to be a secret organization that committed satanic rituals and was operated by the U.S. government. He was the author of the best-selling book How to Locate Anyone Anywhere.
Ted Gunderson joined the Federal Bureau of Investigation in December 1951 under J. Edgar Hoover. He served in the Mobile, Knoxville, New York City, and Albuquerque offices. He held posts as an Assistant Special Agentin-Charge in New Haven and Philadelphia. In 1973 he became the head of the Memphis FBI office and then the head of the Dallas FBI office in 1975. Ted Gunderson was appointed the head of the Los Angeles FBI in 1977. In 1979 he was one of a handful interviewed for the job of FBI director, which ultimately went to William H. Webster.
After retiring from the FBI, Gunderson set up a private investigation firm, Ted L. Gunderson and Associates, in Santa Monica, California. In 1980, he became a defense investigator for Green Beret doctor Jeffrey R. MacDonald, who had been convicted of the 1970 murders of his pregnant wife and two daughters. Gunderson obtained affidavits from Helena Stoeckley confessing to her involvement in the murders which she claimed had in actuality been perpetrated by a Satanic cult of which she was a member.
He also investigated a child molestation trial in Manhattan Beach, California. In a 1995 conference in Dallas, Gunderson warned about the supposed proliferation of secret occultist groups, and the danger posed by the New World Order, an alleged shadow government that would be controlling the United States government. He also claimed that a "slave auction" in which children were sold by Saudi agents to men had been held in Las Vegas, that four thousand ritual human sacrifices are performed in New York City every year, and that the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City was carried out by the US government. Gunderson believed that in the United States there is a secret widespread network of groups who kidnap children and infants, and subject them to ritual abuse and subsequent human sacrifice. Part of this is believed to have been conducted by the CIA in an operation called The Finders.
