On November 17, 2025, 30-year-old man Mark Clewis Jr from Oklahoma City, Oklahoma, was shot at an apartment complex in the city's northwest side and later died at the hospital. In the pre-dawn hours, around 3:30 a.m., police were called to the Meadow Apartments on Melrose Lane near Rockwell Avenue after reports of gunfire and a wounded person. Responding officers searched the breezeways and interior corridors of the complex before finding Clewis inside an apartment, gravely injured from a
gunshot wound. He was rushed by ambulance to a local hospital, but despite medical efforts, he succumbed to his injuries the same day, his death later recorded among the city's growing list of fatal shootings for 2025.
In the immediate aftermath, detectives treated the complex as an active crime scene, stringing tape across the breezeways and concentrating their work around the interior courtyard where neighbors had first heard the shot and seen movement in the early morning darkness. Initial news reports emphasized how little was known: officers could not yet say what had led to the confrontation, whether the shooting sprang from a personal dispute, a chance encounter, or something more planned. At first, police had no clear description of a suspect to share with the public, and they appealed for witnesses to come forward, asking anyone who had seen or heard anything unusual around the time of the gunfire to contact Crime Stoppers or the department's homicide tip line.
Within two days, however, the narrative shifted from uncertainty to pursuit and arrest. Investigators identified 47-year-old Allen Sioux as the man they believed had shot Clewis during the incident at the northwest Oklahoma City complex. According to police, Sioux fled the scene in the chaotic moments after the shooting, disappearing before officers arrived and leaving behind little more than shell casings, a wounded victim, and the frightened accounts of residents awakened by the commotion. Detectives worked quickly, securing a warrant and tracking Sioux to the 2400 block of Southwest 45th Street, where he was taken into custody on Tuesday, November 18.
Once arrested, Sioux was booked into the Oklahoma County Detention Center on a charge of first-degree murder in connection with Clewis's death, and the case was formally counted as Oklahoma City's 63rd homicide of the year. Even with a suspect behind bars, police made it clear that their work was far from over: they continued to gather evidence, reconstruct the sequence of events inside and around the apartment, and seek additional witnesses who could clarify what brought Clewis and Sioux together in those final moments. Public appeals urged anyone with lingering information—no matter how small it might seem—to step forward, underscoring that, while an arrest had been made, the full story of what happened to Mark Clewis Jr in that northwest Oklahoma City apartment before dawn on November 17 was still being pieced together.
