A Starr County man is facing charges after admitting his role in a scheme to smuggle thousands of rounds of ammunition into Mexico. Jose Antonio Rivera will appear in federal court today for a detention hearing. Investigators began looking into Rivera’s activities last year after receiving a report that he ordered six-thousand rounds of ammunition for delivery to his home. During an interview, Rivera admitted that the ammo would be hidden in a vehicle and smuggled across the border. Investigators say Rivera also admitted to buying more than 40-thousand rounds of ammunition as part of the smuggling scheme.
