On the night of June 6, 1986, in Richmond, Missouri, 40-year-old Sherry Wrisinger and her 16-year-old daughter Johnna disappeared after both were reported to have headed home just before midnight. The two older daughters were away that weekend, and the pair were not reported missing until September 16, 1986, when a brother-in-law filed the missing persons report.

Their personal effects and clothing were left behind, Sherry’s car stayed at the house, and uncashed paychecks for both were found — details family say were uncharacteristic for Sherry, who had a long attendance record at the Shirkey Leisure Acres nursing home. A story from husband Ronald Wrisinger claiming Sherry had left with a wealthy veterinarian proved false. In the months before the disappearance the family received anonymous threatening letters and suffered vandalism to vehicles; the FBI opened an extortion inquiry but no suspects were identified.

Ronald Wrisinger was arrested in May 2009 on two counts of first-degree murder after a reinvestigation reportedly uncovered new evidence; he pleaded not guilty and charges were dropped in April 2010 after the death of a key witness. The bodies of Sherry and Johnna have never been found. Does anyone have information about the family, the 1986 threats or the vandalism that might help explain what happened?
