Dallas Police release video of fatal shooting inside Children's Medical Center garage

Dallas police release body camera video and new details about suspect shot outside Children’s Medical Center.

North Texas police released new details Monday about the man fatally shot by officers outside Children’s Medical Center last week.

Dallas police held a news conference Monday afternoon at headquarters and shared portions of dash camera footage and several angles of officers’ body-worn cameras leading up to the shooting of 39-year-old Diamon-Maziarre Robinson.

In the video, officers are seen following Robinson through downtown Dallas in a car police said was flagged for stolen plates. The footage then cuts to the parking garage at Children’s Medical Center, where Robinson is seen sitting inside a vehicle as officers shout commands for him to get out with his hands up.

While exiting the car, Robinson appears to reach for his waist and point what appears to be a firearm before the video freezes and gunshots are heard.

“During that time, officers offered opportunities to speak with family members to resolve the situation peacefully which is a common practice during negotiations,” said Executive Assistant Chief Terrence Rhodes with the Dallas Police Department.

Police said Robinson had two active theft warrants at the time of the shooting: a 2014 auto theft warrant and a 2016 theft warrant for cashing forged checks. Detectives were also investigating evidence they said suggested Robinson was using a false identity and impersonating a federal agent.

“He was very good at hiding his true identity. Through great police work through the intelligence unit and the Irving police department. Through technology, we were able to determine who his real identity was,” said Deputy Chief William H. Griffith with the Dallas Police Department.

Investigators said Robinson used fictitious information and wore police-style uniforms while presenting himself as a federal agent. Police said he also used the alias “Mike King” and created fake businesses to hire sworn police officers for off-duty work through a service called RollKall.

Authorities said additional evidence was recovered after a search warrant was executed at Robinson’s apartment.

“There’s also his IDs that he had. The ID cards were also found inside the vehicle as well along with some badges,” Griffith said. “We executed a search warrant on Mr. Robison’s apartment that afternoon and recovered additional badges and additional firearms.”

Sources told NBC 5 Robinson worked as a security guard for U.S. Rep. Jasmine Crockett. Crockett later confirmed the connection in a statement.

“We are saddened and shocked by some of the concerning revelations. Our team followed all protocols outlines by the House to contract additional security. We were approved to use this vendor who also provided security services for additional entities in the local community and worked closely with law enforcement agencies including Capitol Police.”

“Mike had been in and around our team for years. There was never any reason to suspect that he wasn’t who he held himself out to be. He never endangered our team, worked diligently, coordinated with local law enforcement and maintained positive relationships throughout the community.”

“What we are learning about his past doesn’t fit the person we came to know as Mike King. His death evokes a range of emotions. Our hearts grieve the loss of someone we knew and the lost good that could have come from his redemption.”

Federal Election Commission finance records show a $340 payment last year for security services to “Mike King.”

Police said Robinson may have used the RollKall platform to hire off-duty officers. Dallas police said the department has used the service since November 2024 and that Robinson, posing as Mike King, began using the system in April 2025.

RollKall released a statement saying Robinson was not connected to the company.

“RollKall is a technology platform used by law enforcement agencies, businesses, and organizations to manage off-duty assignments. The individual in question is not, and has never been, a RollKall employee. We can also confirm that at no point was this individual able to access or disseminate the personal data or personally identifiable information of any other person on the platform.”

Dallas police said Robinson had a professional relationship with at least one sworn officer months before the shooting. Investigators said the officer recognized Robinson during the investigation and disclosed their prior interactions.

Detectives said they are interviewing additional potential witnesses who may have also had contact with Robinson.

The investigation remains ongoing.
