Dione Lynne Fox was 25 when she was last seen in Tiawah, Oklahoma, on September 1, 1996. She had divorced in 1993 and sought a protective order against her ex-husband that year; in May 1996 she reported he assaulted her and threatened her life, and charges were filed. Dione vanished before she was scheduled to testify and the charges were later dismissed.

Eight months after her disappearance, her car was found abandoned in Noel, Missouri, where her mother lived; the keys and her purse were inside. In 2014 the Rogers County Sheriff’s Office reopened the case and executed a search warrant on a 20-acre property in the Tiawah area belonging to the ex-husband’s family, with assistance from multiple agencies, but the search turned up nothing. Her ex-husband has denied wrongdoing and said she left for her mother’s home; family members say she would not have abandoned her children. No activity on her Social Security record has been recorded since 1996.

Anyone with information about Dione’s movements in 1996 or who may have seen her vehicle in Noel is asked to come forward.
