Former Security Guard For Rep. Jasmine Crockett Fatally Shot During Police Standoff In Dallas

Diamon-Mazairre Robinson, 39, had an active federal warrant for impersonating a police officer.

A former security guard for Rep. Jasmine Crockett was fatally shot Wednesday, March 11 during a police standoff in Dallas.

CBS News Texas reported that Diamon-Mazairre Robinson, 39, recently served as a member of the politician’s security team and went by the alias of Mike King.

A federal investigation into Robinson led to a standoff with the Dallas Fugitive Unit, who had an active warrant for Robinson impersonating a police officer. Robinson reportedly had seven arrests for theft, all occurring between 2009 and 2012.

CBS News reports that he pleaded guilty to his sentences for those convictions, but was fined no more than $2,500 and sentences of probation from 1 to 5 years, and in one case, 10 years.

He used an alias to launch several businesses, including helping off-duty cops find security gigs.

Officers discovered Robinson as he barricaded himself inside a vehicle parked at the Children’s Medical Center in Dallas.

CBS News reported that officers used tear gas to lure Robinson out of the vehicle. Robinson exited the car, pointing a gun at the officers.

During a press conference shared on social media, Chief Daniel C. Comeaux of the Dallas Police Department confirmed Robinson died during the standoff.

Before his death, Robinson, using his alias to impersonate a police officer himself, also oversaw security teams at hotels across downtown Dallas, as well as his local church. Despite his criminal background, Robinson was able to gain access to the high-profile security gig with Crockett.

Robinson worked with Crockett as recently as this year. The local news outlet confirmed his identity in pictures with the congresswoman during her failed run for U.S. Senate.

Neither Crockett nor her press team has released a comment on Robinson.
