It's an image that many in the Bay Area will never forget. In 1998, a San Francisco row house exploded, and investigators blamed the blast on illegal fireworks. Seto stood at ground zero at the time of the blast. He was thrown through two walls, into the building next door, and was burned over most of his body. But the I-Team obtained documents that raise serious questions about Mr. Seto's claims.
Arson investigators pinpoint the blast to a crater in the concrete floor of the house.
It's in a storage area under the stairs, through a door, and many feet away from the building's gas appliances. It pointed to fireworks. Also, in the rubble of the blast site, arson investigators found a receipt for the purchase of 100 pounds of chemicals that can be used to make explosives. The receipt was issued to one of Tony Seto's friends. Still, with all the evidence and a complete arson report, the San Francisco District Attorney's Office has not made a single arrest.
