MCALLEN - A father and son were charged in connection with the shooting of a federal agent. Pedro Alvarado, 41, and Arnoldo Alvarado, 18, are expected to appear before a judge this morning. A minor identified in connection with the crime was turned over to state authorities. He'll face a judge later this afternoon.

The shooting of Homeland Security Investigations Agent Kelton Harrison happened near Hargill Tuesday, while he was conducting surveillance near FM 493 and Cemetery Road. We're told the surveillance was in anticipation of a suspected drug deal. Investigators say another vehicle approached Harrison and opened fire.

In the criminal complaint, Arnoldo Alvarado stated his father had told him and the minor to get guns because of a suspicious vehicle near their home. He admitted getting a 9mm handgun and said the minor had a .22 caliber rifle. Arnoldo Alvardo told investigators he and the minor fired at the vehicle several times.

Investigators say Harrison drove away and Pedro Alvarado chased him north on FM 493. Arnoldo Alvarado said he and the minor continued to fire at Harrison's vehicle.

Harrison lost control of his vehicle. Other agents arrived and discovered he'd had been shot at least once. He was taken to a McAllen hospital.

HSI special agents later searched a home in Hargill and found the Alvarados and the minor. They were taken into federal custody for further questioning. The two men are expected to appear before a judge this morning. They were charged with assault of a federal officer and knowingly using and carrying a firearm during, and in relation to, a crime of violence.

CHANNEL 5 NEWS will have a crew during the Alvarados' court hearing to gather the very latest details.

Meanwhile, the injured agent is recovering from the shooting. He's reported to be in stable condition and improving.
