A federal assault charge in Dallas, a Border Patrol push against smuggling networks, and an international extradition case headline this week’s Texas Takedown.
Deputy U.S. Marshal Injured In Dallas Truck Assault Case
Federal prosecutors allege that a 43-year-old Guatemalan national struck a Deputy U.S. Marshal with a pickup truck while attempting to flee a traffic stop in Dallas.
Senel Galiano Sagastume was charged by federal complaint on March 24 with forcibly assaulting a federal officer and inflicting bodily injury, according to the U.S. Attorney’s Office for the Northern District of Texas. Prosecutors claim officers initiated a traffic stop and, after Sagastume and his passengers allegedly refused to roll down the windows, breached the vehicle’s glass.
Authorities allege Sagastume then accelerated the truck, wedging a uniformed Deputy U.S. Marshal between his vehicle and a law enforcement unit, causing bodily injury. The complaint further alleges he fled to an apartment complex in Richardson, where he was arrested following an hours-long standoff.
Sagastume appeared before a magistrate judge in Dallas on March 25 and remains in federal custody. If convicted, he faces up to 20 years in prison. Court records obtained by The Dallas Express indicate Sagastume has received court-appointed counsel.
Federal officials emphasized that the complaint is an allegation and that the defendant is presumed innocent unless proven guilty.
Border Patrol Continues To Dismantle Criminal Smuggling Networks
U.S. Border Patrol officials say enforcement efforts remain focused on dismantling criminal networks, as highlighted in a recent public statement by Chief Patrol Agent Jared C. Ashby.
Ashby wrote, “Targeting criminal organizations at the border, U.S. Border Patrol is focused on disrupting their networks, resources, and leadership. We’re dismantling smuggling operations and protecting our communities. Our mission is to secure the border and keep America safe.”

He attached an infographic that included a suspect photo and an inscription that authorities seized almost 50 pounds of marijuana, valued at nearly $40,000.
Honduran National Extradited to Texas on Cocaine Trafficking Charges
A Honduran national accused of participating in an international cocaine trafficking conspiracy has been extradited to Texas to face federal charges, prosecutors said.
The U.S. Attorney’s Office for the Eastern District of Texas announced in a press release that Baldemar Roque Negrete, 52, was transferred from Guatemala to the United States on March 20. He had previously been indicted in August 2019 on charges of conspiracy to manufacture and distribute five kilograms or more of cocaine intended for importation into the United States.
Negrete made a court appearance in the Eastern District of Texas on March 24. If convicted, he faces a potential sentence of life in federal prison.
Court filings obtained by The Dallas Express indicate that the magistrate set the discovery process into motion on March 24.
Prosecutors said the case is part of a broader federal initiative targeting transnational criminal organizations, including drug cartels and trafficking networks. Multiple agencies, including the Drug Enforcement Administration and the Federal Bureau of Investigation, were involved in the investigation, along with international partners.
Officials noted that the indictment is an allegation and that Negrete is presumed innocent unless proven guilty in court.
