On this day in history, August 22, 1992... Vicki Weaver was shot and killed by FBI sniper Lon Horiuchi during an 11-day siege at her home at Ruby Ridge, Idaho. The incident began when Randy Weaver failed to appear before a court for firearms charges. When six members of the U.S. Marshals Service initially entered the Weaver property, a shootout resulted in the deaths of Deputy US Marshal William Francis Degan, Weaver's son Sammy, their dog, Striker. In 1994, it was determined that the rules that allowed the "second shot" to occur (which killed Vicki) did not satisfy constitutional standards for legal use of deadly force. Motivated by his dislike for the U.S. federal government and angry about its handling of the Waco siege in 1993, Timothy McVeigh was also motivated to bomb the Alfred P. Murrah Federal Building in downtown Oklahoma City because of the Ruby Ridge incident.
