Isiah Thompson was 22 when he was fatally shot on November 12, 2021, in a strip mall parking lot in Far East Dallas. Officers found him on the ground with multiple gunshot wounds; he was pronounced dead at a hospital. A witness told investigators Thompson said Geo shot him just before he died and described an encounter with two men in a pickup truck after which Thompson tried to flee and was followed and shot. The witness provided a partial license plate that investigators tied to one of the suspects.

Dallas police arrested 17-year-old Luis Angel Martinez and 19-year-old Geovani Arreguin on murder charges. Both men sought medical attention for gunshot wounds and were taken into custody. According to Martinez in a statement to detectives, the two had gone to the parking lot to sell a gun to Thompson; Martinez said Thompson turned the gun on Arreguin and shot him in the arm and leg, then Martinez grabbed a gun from Arreguin and shot Thompson as he tried to run away, firing until his gun was empty. Martinez and Arreguin reportedly discarded Thompson’s phone and the handgun by throwing them from their vehicle.

Bail was set at $300,000 for Arreguin and $200,000 for Martinez. The investigation into the circumstances leading up to Thompson’s death was ongoing. If anyone has information about the shooting or the events that preceded it, please come forward.
