Details of Disappearance
Donald's older sister, 26-year-old Paula Phillips
, disappeared from Tulsa, Oklahoma on October 3, 1991. Donald reported her missing on October 7. When police attempted to interview him three days later, October 10, they were unable to locate him.
Donald and Paula have not been seen since. A third Phillips sibling, 21-year-old Londa
, disappeared from Tulsa thirteen months later, on November 22, 1992.
Authorities believe the disappearances may be connected to each other and to drug activity. They have persons of interest in the cases, but have never identified anyone as a suspect or made any arrests. All three cases remains unsolved.
