DeQuinn L. Mackey

DeQuinn L. Mackey, a young man remembered by loved ones as "extremely funny" and the "life of the party," was just 19 years old when his life was cut short. Known to some by the affectionate nicknames "Quinnie" and "Bubba," he was also cherished as "the best big brother," a young Black man with a promising life ahead of him in his Oklahoma City community. His sudden death left a void for those who knew and loved him, who remember a life defined by laughter and connection, not the violence that ended it.

In the pre-dawn hours of Saturday, October 4, 2014, a dispute erupted at the Quail Lake Apartments in a northwest Oklahoma City neighborhood near North Pennsylvania Avenue and N.W. 140th Street. Shortly before 1:30 a.m., an argument, reportedly over a stolen cellphone, escalated with tragic finality. Gunshots rang out in the apartment complex, striking DeQuinn and a second individual.

In the immediate aftermath, DeQuinn and the other victim, 18-year-old Natalie Martin, were not transported by ambulance but were instead driven to a local hospital in a private vehicle. Upon their arrival, medical staff pronounced DeQuinn L. Mackey dead from his injuries. Martin was treated for a gunshot wound to her hand and was later released. DeQuinn’s death was recorded as the 45th homicide in Oklahoma City that year, a statistic representing a profound personal loss for his family and friends.

The Oklahoma City Police Department launched an immediate homicide investigation. Detectives worked quickly to identify a person of interest based on information gathered at the scene. Their investigation pointed to another 19-year-old, Kamron L. Carter. The day after the fatal shooting, on Sunday morning, officers located Carter and apprehended him during a traffic stop in the city.

Following his arrest, Kamron Carter was taken into custody by the Oklahoma City police. He was subsequently booked into the Oklahoma County Jail on a formal complaint of first-degree murder in connection with the shooting death of DeQuinn Mackey. The swift arrest brought a suspect into the justice system, marking the next phase in a case that began with a senseless argument and ended in a young man’s death.

The case against Kamron Carter proceeded through the Oklahoma County court system. In October 2015, Carter entered a blind plea to a reduced charge of first-degree manslaughter. A blind plea means he did not have a pre-arranged sentencing agreement with the prosecution. In December 2015, a judge sentenced him to serve 15 years in prison for the killing of DeQuinn Mackey. As of November 2026, Kamron Carter is incarcerated with the Oklahoma Department of Corrections, with a projected release date in 2028. For the family and friends of DeQuinn, the resolution of the court case does not erase the enduring pain of his absence, leaving them with memories of a vibrant young man who was taken from them far too soon.
