Terry Nichols' oldest son was found guilty Tuesday in Las Vegas of assault with a deadly weapon, resisting arrest, battery and possession of a stolen car, officials said.
Josh Nichols, 23, will be sentenced April 26.
He was charged after two Las Vegas police officers spotted him at a gasoline station Oct. 2 getting into a stolen car. Police said he fled in the Toyota Supra a short distance, dragging one officer. The other ended up upside down, with his legs out the car's sunroof.
Jurors found him not guilty of attempted murder of the officers.
His father, Terry Nichols, 50, is serving life sentences with no possibility of release for his role in the deadly 1995 attack on the Oklahoma City federal building.
