On April 3, 2006, 69-year-old Walter Brown and his wife, Grace, were found bound and shot to death in their North Atlanta Avenue home in Tulsa. A friend discovered the couple and notified police, who described the scene as one of brutal violence. Investigators believe robbery was the motive, though many details about what happened inside the house remain unclear.

An early lead sent detectives to a Tulsa casino after an employee reported activity on Grace Brown’s player card after the estimated time of death. That turned out to be a false record created by the casino’s internal inquiry, and the detour cost investigators hours and resources. No arrests have been announced and no suspects have been publicly identified.

Does anyone who lived in or near North Atlanta Avenue in April 2006 recall unusual visitors, vehicles, or other activity that could help solve this case?
