Jury trial starts for man accused of killing Uber driver Robert Diaz on San Antonio’s Northeast Side
Case moves from investigation to courtroom nearly three years after March 2023 shooting
A Bexar County jury trial is underway for a man charged with murder in the 2023 fatal shooting of a San Antonio Uber driver on the city’s Northeast Side. The defendant, Dominique Dashon Croom, is accused of shooting Robert Carbonell Diaz, 37, while Diaz was working as a rideshare driver.
Croom was taken into custody on March 16, 2023, roughly a week after the shooting, and was later booked into the Bexar County Jail. Court records in the case reflect a $200,000 bond.
What investigators say happened on March 9, 2023
The shooting occurred around 8 p.m. on March 9, 2023, near the intersection of Gibbs Sprawl Road and Castle Cross Drive. Investigators reported that Diaz was found unresponsive inside his vehicle and was transported to a hospital, where he died.
Authorities have alleged that Diaz was driving for Uber at the time and was transporting Croom when the shooting occurred. A police report described witnesses hearing multiple gunshots and then seeing a person running away from Diaz’s vehicle.
Location: Gibbs Sprawl Road and Castle Cross Drive area, Northeast Side
Time reported: about 8 p.m., March 9, 2023
Victim: Robert Carbonell Diaz, 37
Defendant: Dominique Dashon Croom (age publicly reported as 33 at the start of the 2026 trial)
Evidence and issues the jury is expected to weigh
The case is centered on evidence assembled in the immediate aftermath of the shooting, including witness accounts and video reviewed by investigators during the manhunt that led to Croom’s arrest. Prosecutors are expected to present testimony and exhibits intended to establish what happened inside or near the vehicle, how Diaz was shot, and how investigators linked the suspect to the killing.
As with any criminal trial, jurors are tasked with evaluating the credibility of witnesses, the reliability of any video or physical evidence introduced in court, and whether the state has met its burden of proof beyond a reasonable doubt.
The defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt.
Why the trial matters for San Antonio’s rideshare workforce
The trial highlights the risks faced by app-based drivers who routinely transport unknown passengers. The allegations in this case involve violence during an active ride, placing renewed attention on passenger screening limits, the role of in-car and nearby surveillance video, and how quickly investigators can reconstruct events when shootings occur in public corridors.
The proceedings are expected to continue with witness testimony and additional evidence presentations before the case is submitted to the jury for deliberations.
