John Peter Mejlaender, 60, was found dead inside his apartment at 8311 E. 66th Street in Tulsa on November 21, 1988, after a co-worker who had been unable to reach him checked on him. Investigators determined he died from gunshot wounds and ruled the case a homicide.

Police say a valuable piece of art was missing from the apartment, and robbery has been considered as a possible motive. Mejlaender was described as wealthy at the time of his death. Despite investigative efforts, no suspects have been publicly identified and no arrests have been announced, and the case remains open.
