Kimberly Doreen Mullens was 32 when she vanished from her Tulsa, Oklahoma, apartment in the summer of 1998. Also known as Kim and a member of the Cherokee Nation, she was last seen on or around July 1, 1998. At the time she was described as 5 feet 4 inches, 120 to 125 pounds, with shoulder-length brown hair, blue eyes and a left-shoulder tattoo reading Lee’s Wife.

Kimberly was mother to four children, including a newborn born two weeks before her disappearance. Her husband told police they had a heated argument the night she was last seen and that she left him for another man; family members found that explanation hard to accept because she had left behind her purse and personal belongings and because they described the marriage as abusive. Her husband has been named a person of interest and foul play is suspected. DNA from family members has been submitted for comparison if unidentified remains turn up.

The case has remained cold despite tips and follow-ups. If anyone knew Kimberly, saw her around July 1998, or has information that could help her children and family find answers, please come forward.
