Johnna Wrisinger and her mother Sherry were last seen in Richmond, Missouri at around midnight on June 6, 1986. Sherry had played cards with some female friends that evening, while Johnna had a date and was dropped off at home before curfew. They have not been seen or heard from since.

Initially, Sherry's husband, Ronald D. Wrisinger, claimed that his wife had left him for a veterinarian and taken Johnna with her, but they never arrived at their destination. However, their disappearance was soon considered a case of foul play.

Sherry and Johnna left all their clothes behind, as well as uncashed paychecks from their respective jobs. Although Ronald filed for divorce later in 1986, it was granted in December, and he was ordered to pay child support for Johnna, but Sherry never received the money. The family received anonymous threatening letters and reports of car vandalism months before the women's disappearance, which investigators believed may have been related.

In May 2009, Ronald was charged with the first-degree murder of both Sherry and Johnna, but the charges were dropped in April 2010 due to the death of a key witness. Ronald has always maintained his innocence, and no one else has been charged in connection with the case. Sherry and Johnna's bodies have never been found.

Authorities still suspect foul play, and the case remains unsolved. Anyone with information on this case is urged to contact the Richmond Police Department. A photo of Ronald at the time of his arrest is available in connection with this case.
