MCALLEN, Texas (AP) The final defendant in a South Texas drug and gun smuggling case that included two sheriff's deputies is scheduled to go to trial in federal court.

Trial is to begin in McAllen on Tuesday of the case against Jose Luis Tovar of Mission. A federal indictment accuses him and his brother of selling six guns to undercover Drug Enforcement Administration agents last May.

His brother, Jerry Tovar, later pleaded guilty to weapons and drug conspiracy charges and awaits sentencing.

The investigation later ensnared two Duval County sheriff's deputies who planned to use a police vehicle to smuggle cocaine from the Tovar brothers north from the border. The deputies pleaded guilty to drug charges last month.
