Demarcus Miller was arrested nearly 16 months after Nathaniel Ogbolu was fatally shot during an attempted robbery at a Dallas 7-Eleven.
DALLAS, TX — Five people identified Demarcus Miller as a suspect at different points before authorities arrested him in the 2023 killing of 7-Eleven clerk Nathaniel Ogbolu, according to an arrest affidavit obtained by FOX 4 and records released by Dallas police.
Miller, 38 at the time of his arrest, was taken into custody Oct. 9, 2024, by the U.S. Marshals North Texas Task Force and charged with capital murder. The arrest came nearly 16 months after Ogbolu, 54, was shot during an attempted robbery at a convenience store in the 400 block of North Hampton Road. The affidavit described a series of tips that began within days of the killing and continued into 2024, including statements from people who said they recognized Miller from surveillance footage or information surrounding the case.
Dallas police said officers were called to the store at about 6:08 a.m. June 19, 2023. Investigators said a man entered the business, pointed a gun at Ogbolu and demanded money from the register. Before Ogbolu could open it, the robber shot him several times, police said. The gunman also fired at another person inside the store but missed. Ogbolu was taken to a hospital, where he died. The attacker fled on foot.
Police released surveillance video and images in the days after the shooting in an effort to identify the gunman. The footage showed a person whose face was obscured by clothing, including a mask. Dallas homicide Detective David Grubbs later appealed publicly for information, saying Ogbolu was working when he was killed and that his wife was inside the store when the shooting occurred. Customers and people in the neighborhood described Ogbolu, who was also known as “Natty,” as a familiar and welcoming presence at the store.
According to the arrest affidavit reported by FOX 4, one person gave police Miller’s name and social media information within days of the killing. A second person contacted investigators around the time police renewed their public appeal in late June 2023. That person told detectives that Miller had acknowledged involvement after showing her publicly released footage of the crime, according to the affidavit. Two additional people later identified Miller during the summer of 2023.
Investigators had an opportunity to question Miller the following month. He was arrested in July 2023 on an unrelated allegation involving assault of a family member, according to FOX 4’s account of the affidavit. Dallas detectives questioned him about Ogbolu’s killing while he was in custody. Miller denied involvement. The unrelated assault case was later dropped at the request of the apparent complainant, and Miller was released. He had not yet been charged in the 7-Eleven case.
Police also seized Miller’s cellphone during the earlier investigation, according to the affidavit. Investigators said the device contained photographs showing him in a black ski mask and gray hoodie shortly after the robbery. Authorities had previously asked the public to focus on the clothing worn by the person shown in the surveillance footage. The affidavit did not establish by itself that the clothing in the photographs was the same clothing used during the crime, and the allegations against Miller remain accusations unless proven in court.
A fifth witness was interviewed in October 2024, according to FOX 4. That person identified Miller as the robbery suspect and told investigators she had seen him wearing clothing matching what was shown in surveillance images on the night before or around the time of the killing. Police arrested Miller soon afterward. Dallas police publicly confirmed that the U.S. Marshals task force took him into custody on a capital murder charge but did not disclose how authorities ultimately located him.
The timing of the arrest drew attention because investigators had received several identifications and had questioned Miller long before he was charged. The publicly reported affidavit shows that detectives accumulated witness statements and cellphone evidence over the course of the investigation, but available records do not explain in full why authorities waited until October 2024 to seek or execute the capital murder arrest. Police did not announce that the earlier witness statements alone were sufficient to establish probable cause for an arrest at the time they were received.
At the time of his 2024 arrest, Miller was being held in the Dallas County jail on a $2.5 million bond, according to contemporaneous reports. Dallas police listed him as charged with capital murder in Ogbolu’s death. Searches of publicly available reporting and police material reviewed for this story did not identify a later verified trial verdict or other final disposition in the case. Miller is therefore described as accused, and the charge should not be treated as proof of guilt.
