So the Touchstone Pistachio Company, of Fresno, contacted authorities. It led to the arrest Friday of Alberto Montemayor, 34, of Montemayor Trucking in Delano, reports CBS Fresno affiliate KGPE-TV. He was booked in Tulare County. Officials said leads in Fresno and in Kern County helped detectives discover that the tractor-trailer with the nuts inside had been moved from a Montemayor Trucking lot to an area nearby. Detectives said pistachios from one-ton — 2,000-pound sacks were being put into smaller bags for resale. Authorities said the pistachios still in the tractor-trailer were returned to Touchstone.
