In the early morning hours of October 19, 2003, officers responding to a man down call at 2627 E. 29th Street in Tulsa found 41-year-old Mark Phillips dead inside his home. The scene indicated a violent attack, and investigators determined Phillips had been strangled to death.

Initial detectives processed the scene but uncovered few leads, and the case went cold despite investigative work in the days and weeks afterward. The homicide remains unsolved and has since been assigned to the Tulsa Police Department’s Cold Case Unit. No arrests have been announced and no suspects have been publicly identified.

Anyone who knew Mark or who has information about events around that address on the morning of October 19, 2003, is asked to contact investigators.
