A 76-year-old man who police say barreled into a Border Patrol checkpoint in southern Arizona and shot at agents before they fired back is facing federal charges.
Gary Smith of Tombstone was indicted on charges of assault of a federal officer and use of a firearm in a crime of violence.
A magistrate judge ordered Smith detained without bond last week, saying he was a danger to the public. His federal public defender did not respond to an inquiry.
Smith was struck in the arm after a shootout with Border Patrol agents on May 18 at a checkpoint near Tombstone. No agents were injured.
According to a court document, Smith had recently been treated at a mental health facility and told his family he was going to "commit suicide by cop."
