KINGMAN, Ariz. (CNN) -- FBI agents digging in the desert outside Kingman for evidence in the Oklahoma City bombing Thursday found more than 150 pounds of ammonium nitrate buried in the sand, law enforcement sources said.
A bomb made of ammonium nitrate and fertilizer blew up the Oklahoma City federal building April 19, resulting in the deaths of 168 people.
One source told CNN the special FBI unit in the desert is theorizing the ammonium nitrate found Thursday was part of a cache used to test the effectiveness of a fertilizer bomb in advance of the Oklahoma City attack.
The FBI is searching for a duffel bag believed buried in the desert that is thought to contain guns and bomb-making materials, the sources said. The hunt began last week, and there is no indication such a bag has been found.
The Kingman connection to the Oklahoma attack involves the friendship of chief suspect Timothy McVeigh, who has lived in Kingman, and Michael Fortier, a lifelong resident of the remote desert town. Also, Fortier's former next-door neighbor, James Rosencrans, has testified before the grand jury in the case.
