A man who previously worked as a security guard for Rep. Jasmine Crockett was shot and killed during a standoff with police in Dallas on Wednesday night, after authorities say he pointed a gun at officers attempting to apprehend him.
The suspect, identified as 39-year-old Diamon-Mazairre Robinson, had an extensive criminal history dating back more than a decade and was under federal investigation at the time of the confrontation, according to reports from CBS News’ Texas affiliate.
Police said Robinson barricaded himself inside a vehicle in a parking garage connected to Children’s Medical Center Dallas while being tracked by the Dallas Police Department’s fugitive unit. Officers deployed tear gas in an effort to force him out of the car, authorities said. Robinson then exited the vehicle and allegedly pointed a firearm at officers, prompting police to open fire. He was fatally shot at the scene.
Investigators say Robinson had used multiple aliases, including “Mike King,” to conceal his past and gain entry into law enforcement circles in North Texas. Authorities allege he falsely claimed to be a detective with the United States Capitol Police, which ultimately triggered a federal investigation into possible impersonation.
Under the alias, Robinson was able to obtain work providing security services, including a role protecting Crockett, the 44-year-old Democratic congresswoman from Texas. Records cited by local media indicate Robinson had been paid by Crockett’s office for security services as recently as last year, including a payment totaling $340.
Robinson also reportedly operated a website called “Off Duty Police Services,” which he claimed connected law enforcement officers with off-duty security jobs. He allegedly told people he oversaw several security teams working at churches and downtown hotels in the Dallas area.
Court records reviewed by reporters show Robinson had numerous arrests between 2009 and 2012, including at least seven theft cases. He ultimately pleaded guilty to the charges he faced, receiving penalties that included fines of less than $2,500 and probation. His longest sentence was 10 years of probation.
Video previously circulated by local media showed Crockett walking alongside Robinson during a campaign stop tied to her unsuccessful U.S. Senate bid.
It remains unclear how Robinson secured his position working within Crockett’s security detail.
Crockett has not publicly commented on Robinson’s death.
