Robert Diaz

Robert Carbonell Diaz, a 37-year-old Hispanic man from San Antonio, Texas, was working to earn a living as an Uber driver on the evening his life was taken.

The deadly shooting happened shortly after 8 p.m. on March 9, 2023, while Diaz was transporting a passenger on the city’s Northeast Side. Near the intersection of Gibbs-Sprawl Road and Castle Cross Drive, people in the area heard several gunshots and then saw a person running away from Diaz’s vehicle. Arriving San Antonio police officers found Diaz unresponsive in the driver's seat with multiple gunshot wounds. He was rushed to a local hospital, where he was pronounced dead.

Investigators quickly determined that Diaz had been on an active Uber trip when he was killed. The passenger associated with the ride was identified as Dominique Croom. Through witness interviews and video evidence that showed a man matching Croom’s description fleeing the scene, police identified him as the primary suspect. Seven days after the shooting, on March 16, 2023, authorities arrested Croom, then 30 years old. He was charged with murder and criminal trespass and booked into the Bexar County jail on a $200,000 bond.

Dominique Croom’s murder trial began in Bexar County’s 175th Criminal District Court in early 2026. Over four days, prosecutors presented evidence they said proved Croom killed Diaz, including DNA, fingerprints, and surveillance video of Diaz picking up a passenger. The court also heard testimony that Croom’s cellphone was recovered from the back of the victim’s vehicle, where blood was also found.

On February 6, 2026, the jury found Dominique Croom guilty of murder. As the verdict was read, Croom stood expressionless while members of Robert Diaz’s family cried and embraced in relief. On March 20, 2026, a judge sentenced Croom to life in prison. Following the sentencing, Bexar County District Attorney Joe Gonzales stated, “Robert Diaz was going about his day, working to earn a living, when his life was taken. Our office is committed to seeking justice for victims and their families, and this case reflects that commitment.” The case was closed as of March 2026.
