Their arrests seemed inevitable.
According to the Dallas Police Department, witnesses saw Alex, 19, walking in the 4800 block of Sunnyvale Street on Thursday afternoon. Police say Griffin-White, 17, began to pursue Alex. The two began arguing before Griffin-White pulled a gun from his athletic pants and shot Alex. Griffin-White then got into a red Chrysler PT Cruiser, police say.
Cops arriving at the scene quickly found surveillance video of the murder, which they edited so as not to show the murder itself and shared with the media and followers of DPD's social media channels.
Shortly after posting photos of the PT Cruiser and the video, DPD received multiple tips that the car belonged to Coleman, 27. Friday afternoon, police found the car at an address provided by a witness. Before they were able to do anything, however, the car took off, followed by a U-Haul truck, police said.
Cops eventually lost the PT Cruiser, but they were able to pull the U-Haul over. The driver told police that he'd been flagged down in downtown Dallas at about 4 p.m. Thursday by a man and a woman in a red PT Cruiser. The pair told the man they were moving and offered to pay him to help them move.
Police continued to watch the address where they'd spotted the PT Cruiser leave. Eventually a white sedan pulled up, and a woman got out before returning to the car. The car drove off, and police followed. Officers pulled the car over and Coleman jumped from a passenger seat and ran, eluding police. The driver of the car told officers police that a woman she didn't know had paid her to drive her to the house and then take her elsewhere to pick up her red PT Cruiser. The driver then took police officers to the car, which was impounded.
Sunday, police arrested Coleman and Griffin-White at an undisclosed location. Over the weekend, social media accounts belonging to the couple had posted about the murder.
Coleman and Griffin-White are both charged with capital murder. Their bails have been set at $500,000 each.
