Dallas police killed a man last week who turned out to be part of Rep. Jasmine Crockett's security team. Authorities confirmed Monday he'd been using a fake name and had a criminal record.

Deadly Standoff Unveils Hidden Identity

SWAT officers shot and killed 39-year-old Diamon-Mazairre Robinson Wednesday night after an hours-long standoff. He'd been going by the name Mike King. When police spotted him driving a GMC Yukon with stolen government plates, they launched a manhunt. Police found him hiding in a hospital parking garage. After negotiators spent hours trying to get him out, officers used tear gas. Robinson came out and pulled a gun on them. They shot him dead. When they searched him, investigators found 11 weapons—including the stolen gun he'd pulled on officers.

It started when Irving police put out a bulletin for a car with stolen government plates. A Dallas cop recognized it—he'd worked a security job with Robinson six months before, back when Robinson was going by Mike King. Dallas police attempted to pull Robinson over on March 11, but he fled, leading to a brief chase before he was located in the parking garage.

The Deception of "Mike King"

For years, Robinson pulled off the fake identity. He used it to run Off Duty Police Services, which hired off-duty cops for security gigs all over North Texas. He told at least some of the officers he worked with that he was a Capitol Police detective—a lie that apparently kicked off a federal investigation for impersonating a cop.

He went further: he invented a fake agency called Specialty Dignitary Police and made ID cards for it. He drove a fake undercover police car and stole license plates from vehicles parked outside a military recruiting office. The whole scheme worked. He became a trusted figure in security circles, managing teams of officers at downtown Dallas hotels and his church.

Rep. Crockett Expresses Shock and Concern

Rep. Jasmine Crockett confirmed Monday the dead man had worked on her security team. She said she was sad and shocked by what came out about who he really was and what he'd done. Her team followed House rules for hiring security contractors, and the hiring was approved.

Crockett, in Congress since 2023, said the picture of Robinson's past didn't match the guy her team actually knew. "The man we knew showed up with respect, care, and commitment to protecting others," she said, adding that he never endangered her team, worked diligently, and coordinated with local law enforcement. She also stated that an initial review of his "limited criminal history" showed no violent offenses.

Crockett pointed out something bigger: Robinson had slipped through the cracks in the vetting system. "The fact that an individual was able to somehow circumvent the vetting processes for something as sensitive as security for members of Congress highlights the loopholes and shortcomings in many of our systems," Crockett stated. She called this "incredibly alarming," particularly for members who receive frequent and credible death threats. She argued the incident shows why Capitol Police should handle security for all members of Congress.

As a former public defender, Crockett talked about believing in redemption and second chances. She said it was sad to think about the good he might've done if he'd gotten that chance.

Extensive Criminal History Detailed

Behind the respectable Mike King persona was a long criminal record going back to 2009. He'd been arrested multiple times for theft across North Texas—Dallas, Duncanville, Irving, Dallas County—and by Texas DPS.

Between 2009 and 2017, he racked up misdemeanor and felony charges. He pleaded guilty to several and got fined up to $2,500 and probation from one to five years—one case hit ten years. When he died, Robinson had two active felony theft warrants from 2017 hanging over him, plus warrants for parole violation, impersonating a cop, and stolen plates.

Nobody figured out who Robinson really was until after Crockett's Senate campaign was already over.
