Operation Backfire is a multi-agency criminal investigation, led by the Federal Bureau of Investigation (FBI), into destructive acts in the name of animal rights and environmental causes in the United States described as eco-terrorism by the FBI. The operation resulted in convictions and imprisonment of a number of domestic terrorists, many of which were members of the Animal Liberation Front and Earth Liberation Front.
In 2004 the FBI merged seven independent investigations from its Portland, Oregon field office and called them Operation Backfire. According to an agency statement, the operational focus is on investigating acts of domestic terrorism, carried out on behalf of two activist groups, the Earth Liberation Front (ELF) and Animal Liberation Front (ALF).
In December 2005 and January 2006, with assistance from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the FBI indicted six women and seven men on a total of 65 charges, including arson, conspiracy, use of destructive devices, and destruction of an energy facility. The defendants were named as Joseph Mahmoud Dibee, Chelsea Dawn Gerlach, Sarah Kendall Harvey (née Kendall Tankersley), Daniel McGowan, Stanislas Meyerhoff, Josephine Sunshine Overaker, Jonathan Paul, Rebecca Rubin, Suzanne Savoie, Justin Solondz, Darren Thurston, Kevin Tubbs, and Briana Waters. A number of other unindicted co-conspirators were also named. A 13th alleged co-conspirator, William "Bill" Rodgers, also known as Avalon, committed suicide while in police custody.
