Mark Clewis Jr., 30, was shot in the pre-dawn hours of November 17, 2025, at the Meadow Apartments on Melrose Lane near Rockwell Avenue on Oklahoma City’s northwest side. Officers responding about 3:30 a.m. found Clewis gravely injured inside an apartment after searching breezeways and interior corridors; he was taken to a local hospital and later died of his wound the same day. Neighbors reported hearing a shot and seeing movement in the courtyard, and police initially had no clear suspect description as detectives treated the complex as an active crime scene and asked witnesses to come forward.

Within two days investigators identified 47-year-old Allen Sioux as the person they believe shot Clewis. Police say Sioux fled the scene and was located on the 2400 block of Southwest 45th Street; he was arrested on November 18 and booked into the Oklahoma County Detention Center on a first-degree murder charge. Authorities continue to gather evidence and seek additional witnesses to establish how Clewis and Sioux came together that night. If anyone has information about what was seen or heard around the Meadow Apartments that morning, please contact Crime Stoppers or the homicide tip line.
