AUSTIN, Texas - Authorities in Texas have ruled arson is the official cause of the fire that destroyed the house belonging to the man who flew his plane into a government tax office.
Austin Fire Department spokesman Andre de la Reza said Thursday that the Feb. 18 blaze was intentionally set. Investigators say Joseph Stack started the blaze, drove to a nearby airport and then flew his single-engine plane into the complex that houses offices of the federal Internal Revenue Service. The crash killed Stack and an IRS employee.
Authorities later found a manifesto from Stack in which he described a long-smouldering dispute with the IRS and hatred of the government.
The family's accountant has confirmed that the Stacks were in the middle of an audit for reportedly failing to report income.
