In the van he abandoned not far from the community center, Furrow left more clues to his motives in the shootings, reports CBS News Correspondent Vince Gonzales. In addition to boxes of ammunition and some survival gear, there was a book in the van written by a leader of the racist Christian identity movement. That same author wrote what has become the hate handbook for violent anti-Semitic zealots who call themselves the Phineas Priests. Furrow may have first come in contact with Christian identity groups as a member of the Neo-Nazi Aryan Nations. He was reportedly a lieutenant in that group's security force in 1995.
Furrow also has a connection to one of the most violent hate groups, The Order.
He recently lived with the widow of that group's founder, Robert Mathews. Mathews was killed in a shoot-out with federal agents in 1984. Last year, Furrow reportedly tried to commit himself to a psychiatric hospital in western Washington, but ended up spending time in jail after pulling a knife on the hospital staff. Furrow pleaded guilty to second-degree assault and was sentenced to five months in the King County Jail. He was released on probation.
