Nationwide — Diamon-Mazairre Robinson, a 39-year-old Texas man who served as a security guard for Congresswoman Jasmine Crockett, was shot and killed by Dallas SWAT officers after a standoff. He had a criminal history and was under federal investigation for impersonating law enforcement.
Robinson, who used the alias Mike King, worked on Crockett’s security team and her recent Senate campaign. Police said he fled into a hospital parking garage on Wednesday night, barricaded himself in a vehicle, and ignored officers’ orders. Tear gas forced him out, but he then brandished a stolen firearm, prompting SWAT to shoot him.
According to CBS News, the Dallas Police Department said Robinson was driving a GMC Yukon with stolen government license plates, triggering a manhunt. Officers recovered 11 weapons from him, including the one used in the standoff.
Robinson’s record shows multiple arrests between 2009 and 2017 for theft and other charges in Dallas, Duncanville, Irving, and by the Texas Department of Public Safety. Despite convictions and probation, he reinvented himself as Mike King and became a prominent security officer for Crockett while also running Off Duty Police Services, a company placing officers in off-duty jobs.
Sources say he claimed to be a U.S. Capitol Police detective and oversaw security teams at events, hotels, and his church, drawing the attention of federal investigators. He also drove a replica undercover police vehicle and advertised security work for high-profile events, including the FIFA World Cup in Dallas-Fort Worth.
Documents show Crockett’s office paid him for security services, though specifics about his hiring and salary are unclear. The office confirmed all protocols were followed and that Robinson never endangered the team.
In a statement, Crockett expressed grief over his death and the “lost good that could have come from his redemption,” emphasizing her belief in second chances. She said Robinson had “worked diligently, coordinated with local law enforcement, and maintained positive relationships throughout the community.”
