Prosecutors in Beaumont say 41-year-old Natividad Ovalle Jr. of Alamo pleaded guilty Tuesday to interstate travel in aid of racketeering enterprise. No sentencing date was immediately set for the driver, who faces up to five years in prison.
Investigators say the truck and trailer were stopped April 14 on Interstate 10 near Orange for an inspection.
Ovalle agreed to let officers search the rig. Authorities located a bag with dozens of taped bundles of cash, adding up to nearly $772,000.
Ovalle says he knew the money was from drug trafficking and that he made other cash-hauling trips, earning at least $15,000 each time.
