Grace Noel Reapp, known as Gracie, was 5 when she and her mother, Grace Marie Reapp, vanished from their Jericho, Vermont, home on June 7, 1978. Michael Reapp reported them missing five days later, on June 11, after an alleged note from Grace said she and her daughter had left voluntarily and did not plan to return. Family and investigators found the circumstances suspicious from the start. Michael, who later admitted to multiple extramarital affairs, filed for divorce ten days after the disappearances, citing desertion.

Searches over the years included digs on the family property, but no trace of Grace or Gracie has ever been recovered. In 2006 Michael was charged with their murders; investigators said he was suspected of killing Grace after she discovered an affair and of killing Gracie because the child witnessed the crime. Michael died by suicide in Arizona in 1997 during a police pursuit after an unrelated carjacking. The disappearances remain unsolved and the family continues to seek closure.
