Illegal Alien Federally Charged With Assault After Allegedly Hitting Deputy U.S. Marshal With Pickup Truck While Fleeing Traffic Stop

An illegal alien who allegedly hit a uniformed Deputy U.S. Marshal with his pickup truck while trying to flee the scene of a traffic stop in Dallas has been federally charged with assaulting a federal officer, announced United States Attorney for the Northern District of Texas Ryan Raybould.

Senel Galiano Sagastume, 43, a citizen of Guatemala illegally residing in the United States, was charged by federal complaint on March 24, 2026. According to the complaint, officers initiated a traffic stop and had Sagastume pull to the side of the road. When Sagastume and his passengers refused to roll down the windows, officers breached the truck windows. Sagastume then allegedly put the Silverado in drive and accelerated toward a uniformed Deputy United States Marshal, wedging him between Sagastume's truck and a law enforcement vehicle and causing bodily injury to the Marshal. Sagastume's actions also caused visible damage to the Marshal's uniform, as depicted in the photos contained in the complaint:

As alleged in the complaint, Sagastume fled the scene to a Richardson, Texas apartment complex and ran inside an apartment. Officers arrested him following an hours-long standoff.

If convicted, Sagastume faces a sentence of up to 20 years in federal prison for the charge of forcibly assaulting a federal officer and inflicting bodily injury. Sagastume appeared before a United States Magistrate Judge in Dallas on March 25, 2026, for an initial appearance on the charges. He remains in federal custody pending further court proceedings.

The Federal Bureau of Investigation-Dallas Field Office and United States Marshal Service conducted the investigation. The United States Attorney's Office for the Northern District of Texas is handling the prosecution.

A complaint is merely an allegation of criminal conduct, not evidence. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
