In the pre-dawn hours of a Saturday in Dublin, Georgia, the life of 31-year-old Jaquan Marquis Coney, a male resident of the city, was tragically cut short by gunfire. On June 14, 2025, at approximately 2:55 a.m., officers from the Dublin Police Department were dispatched to the Riverview Park Apartments at 200 Riverview Park Drive after reports of shots fired echoed through the complex. Upon their arrival at building 218, they discovered Mr. Coney lying on the ground, suffering from multiple gunshot wounds. Despite the immediate aid rendered by the responding officers and his subsequent transport to Fairview Park Hospital, Jaquan Marquis Coney was pronounced dead at 4:07 a.m. by an emergency room doctor. The Georgia Bureau of Investigation was called in to assist the Dublin Police Department with the homicide investigation, and Mr. Coney's body was sent to the GBI Crime Lab in Atlanta for an autopsy.
The investigation swiftly identified two suspects in the fatal shooting. Warrants for murder and aggravated assault were issued for 27-year-old D'Angelo Marquez Martin and 24-year-old Quentavious Mercer. In the days following the shooting, the Dublin Police Department announced that D'Angelo Martin had turned himself in to authorities on the evening of Tuesday, June 17, 2025. However, Quentavious Mercer remained at large, and law enforcement appealed to the public for any information regarding his whereabouts.
The case surrounding Quentavious Mercer takes a complex turn with the high-profile legal troubles of a man with a nearly identical name and matching age from the same area. Quintez Dewayne Mercer, also 24 at the time of the incident, was arrested and, in April 2025, convicted and sentenced to two consecutive life sentences plus 410 years for his role in a separate, gang-related double murder that occurred in Dublin on Easter morning of 2024. While news reports on the Jaquan Coney case name the suspect as 'Quentavious,' the significant overlap in name, age, and location strongly suggests they may be the same individual.
Following the initial announcements of the warrants and the surrender of D'Angelo Marquez Martin, publicly available information regarding the progression of the legal case against him in the death of Jaquan Marquis Coney has been limited. Similarly, while Quintez Mercer is now incarcerated for the 2024 double homicide, specific details regarding his apprehension and any legal proceedings related to the death of Jaquan Marquis Coney are not readily available in public records. The investigation into the death of Jaquan Marquis Coney remains officially open.
