Johnna Wrisinger was 16 when she was last seen in Richmond, Missouri, on the night of June 6, 1986. She was dropped off at her home on Ottman Street just before her midnight curfew after a date; her mother, Sherry, returned home around midnight that same night. Neither was seen again. Both women’s clothing and uncashed paychecks were left behind, a detail that investigators say suggests they had not planned to leave.

Early on Ronald D. Wrisinger, Johnna’s father and Sherry’s husband, told family and authorities that Sherry had left with a wealthy veterinarian and taken Johnna, but investigators found no such veterinarian. The family had also been receiving anonymous threatening letters and experiencing vandalism to vehicles in the months before the disappearance; the FBI investigated possible extortion but no suspects were named and the harassment stopped after the agency got involved.

Rumors that the women were buried under a concrete slab at their home were disproved when the concrete was dated to before June 1986. Ronald Wrisinger was arrested and charged with two counts of first-degree murder in May 2009, but those charges were dropped in April 2010 after a key witness died. Johnna and Sherry have never been found and the case remains open.

If anyone knew Johnna or Sherry, lived in Richmond then, or has information about the threats the family received, please share what is known.
