Fresno County Sheriff Margaret Mims says the suspects carried the meth in a "Superman backpack" that also had diapers in it to conceal the drugs.
"We actually have a drug trafficking organization connected to Mexico. We found Western Union receipts where money was wired to Mexico. They were Mexican nationals that were arrested here illegally."
Deputies also recovered three more pounds of meth and an assault rifle while serving a related search warrant in Orange Cove. Investigators say the suspects will likely face federal charges.
