Investigators arrested a trucker last week after finding 20 kilograms of cocaine hidden in the cab. On Thursday, a state trooper stopped Alfredo Tait on U.S. 281 near San Manuel, according to the criminal complaint against him. Tait was driving a red tractor-trailer with license plates that belonged to another vehicle, according to the criminal complaint. "When asked about his travel itinerary, Tait also provided untruthful responses to Trooper Benavides," according to the criminal complaint. "Tait subsequently admitted that he was lying about his travel itinerary and later stated that he drove the vehicle down specifically for hauling a load of drugs." Agents with the Texas Department of Public Safety Criminal Investigations Division escorted the tractor-trailer to the Pharr-Reynosa International Bridge. A K-9 at the bridge alerted to the tractor-trailer, according to the criminal complaint. An X-ray also revealed an anomaly in the sleeper compartment. Investigators found 19 bundles of cocaine hidden in two mattresses and another bundle inside an air vent, according to the criminal complaint. Tair was charged with possession with intent to distribute more than 5 kilograms of cocaine and conspiracy to possess with intent to distribute a controlled substance. Court records don't list an attorney for Tait, who remains in federal custody.
