Legal name of fugitive killed by Dallas SWAT revealed; had history of arrests before Rep. Jasmine Crockett security role, sources say
A man shot and killed by Dallas police earlier this week was a familiar figure in North Texas law enforcement – and part of the security detail for U.S. Rep. Jasmine Crockett, sources told CBS News Texas.
On Saturday, sources identified the man as 39-year-old Diamon-Mazairre Robinson. He was publicly using the alias "Mike King" and had been using aliases while running a business that placed officers in off‑duty jobs.
Robinson was killed Wednesday night after a standoff with Dallas police SWAT officers. Police said he fled into a hospital parking garage, barricaded himself inside a vehicle, and was forced out by tear gas before pulling a gun on officers.
The Dallas Police Department said on Monday that Robinson was driving a GMC Yukon with stolen government license plates, leading to the manhunt, which ended with him being shot and killed by SWAT officers. Police found 11 weapons in his possession. The one he was holding when shot and killed was stolen, according to authorities
Sources said he was the subject of a federal investigation, in which he was wanted for impersonating a law enforcement officer.
Criminal history reveals multiple arrests
CBS News Texas has been researching Robinson's criminal history, which includes multiple arrests for theft in Dallas, Duncanville, Irving, Dallas County and by the Texas Department of Public Safety.
All of the arrests were between 2009 and 2017 and include misdemeanor and felony charges.
It appears his sentences for those convictions, for which he pleaded guilty, led to fines no more than $2,500 and sentences of probation from 1 to 5 years, and in one case, 10 years.
Despite that criminal background, sources said Robinson was able to forge a new identity as Mike King, where he not only became a prominent figure as a security officer for Rep. Crockett while in office and during her recent U.S. Senate campaign, sources said the convicted felon was also able to run a business placing North Texas law enforcement officers in off duty jobs through his business called Off Duty Police Services.
Some of those officers told CBS News Texas that Robinson, who they knew as Mike King, told him he was a detective with U.S. Capitol Police, which may have led to the federal investigation that resulted in the hunt for him this week.
Trusted role in congressional security
Images obtained by CBS News Texas show Robinson standing close to Crockett at events and on the campaign trail during her recent run for a U.S. Senate seat. Sources said he oversaw teams of security officers at several downtown Dallas hotels and at his church.
Law enforcement sources also said Robinson drove a replica undercover police vehicle and used license plates stolen from cars outside a military recruiting office. Sources said Robinson was also using his law enforcement officer placement service to promote security jobs for the upcoming FIFA World Cup games in DFW for $90 an hour.
His criminal background raises questions about how he managed extra‑duty jobs for police officers and secured a high‑level security role for a sitting member of Congress.
Documents obtained by CBS News Texas show a person named Mike King received payments for "security services" from Crockett as recently as last year. One payment was for $340, but it's unclear how he was hired and how much he was earning as one of her primary security officers.
Officials yet to comment
Crockett's staff told CBS News Texas it's waiting for more information before answering questions.
CBS News Texas has also contacted U.S. Capitol Police about whether Robinson was ever subjected to a criminal background check but have not received a response.
