In the early morning of March 9, 1990, Robert Donald Alexander, 50, was found semi-conscious in the street at 500 East 6th Street under a railroad bridge in downtown Tulsa. He had sustained massive head trauma from a brutal beating. Emergency responders took him to a local hospital, but he died of his injuries and the Tulsa Police Department classified the case as a homicide.

Alexander had recently returned to Tulsa from Indiana and was homeless at the time, staying at the Day Center Homeless Shelter without his family’s knowledge. His children had hired a private investigator to find him only months before the assault. The investigation has remained open but cold; no suspects have been publicly identified and no arrests have been announced.

Anyone with memories of downtown Tulsa around March 9, 1990, who might have seen or heard something about Robert Alexander’s last hours is asked to come forward with information.
