The FBI says it was already conducting a domestic terrorism investigation of an Arizona border vigilante when the man allegedly killed four people and then himself this week.
James Turgal, special agent in charge of the FBI's Phoenix office, tells The Arizona Republic ( http://bit.ly/KnPzO4) that his agency's probe of Jason Todd "JT" Ready had nothing to do with the murder-suicide stemming from a suspected domestic dispute in a Phoenix suburb Wednesday.
Ready was the leader of the U.S. Border Guards, a group of armed civilians that patrols the Arizona desert for illegal immigrants and drug smugglers.
Turgal says the FBI's investigation dated to when Ready was a member of the neo-Nazi National Socialist Movement and continued into his participation with the border group. The probe is based on tips of criminal activity that Turgal would not specify.
The report on the paper's website Saturday says the killings have given the FBI access to Ready's documents and computers.
