Richard Dwane Markham, 48, was found inside his Tulsa home at 625 North 28th West Avenue on October 22, 2010, dead of a single gunshot wound. Family members who could not reach him asked police to check on him; officers who entered the house discovered the fatal wound and quickly ruled the death a homicide. Neighbors remembered Markham as a familiar, steady presence who came and went from the house daily, and his unexpected silence prompted the welfare check that led to the discovery.

The house had a painful history for the neighborhood: a neighbor recalled another homicide there in 1999, the killing of Freda Johnson. The Tulsa Police Department included Markham’s death on its list of unsolved homicides, circulated tip-line numbers and suggested a reward might be available for information leading to an arrest or conviction. No arrests or suspects have been publicly reported and the case remains unsolved.

If anyone knew Richard, his routines, or observed unusual activity around 625 North 28th West Avenue in October 2010, please come forward with what you remember.
