McALLEN, Texas (AP) — A father directed his 18-year-old son and another teen to grab guns and shoot into a vehicle parked near their South Texas home, wounding a federal agent who was conducting surveillance, prosecutors alleged Thursday when filing charges against the two men.

The injured U.S. Immigration and Customs Enforcement agent, Kelton Harrison, was targeted while watching for an anticipated drug deal early Tuesday at a property near Hargill, about 25 miles northeast of the U.S.-Mexico border town of McAllen. Harrison sped away but his pursuers followed, shooting at his vehicle until he lost control.
