McALLEN, Texas (AP) - Testimony enters its third day in the trial of a South Texas man and his son accused in the 2012 shooting of a federal agent who was on drug-patrol duty.

A jury hears more evidence Wednesday in the McAllen trial of Pedro Alvarado and son Arnoldo Alvarado, both accused of wounding Immigration and Customs Enforcement agent Kelton Harrison.

Harrison on Tuesday testified about the night he was shot while maintaining drug-related surveillance.

Harrison testified how early on July 3, 2012, two vehicles chased his near Hargill. The agent says shots from the vehicles wounded him before he veered into a field and fled for his life.

Prosecutors say the Alvarados were involved in drug trafficking, but the defense contends they were suspicious of Harrison’s vehicle and acted out of self-defense.
