In the months following the discovery of the Lady of the Dunes, several detectives worked together to solve the case. Authorities said that she was killed somewhere else, as there were footprints to and from the scene. Her position also seemed posed, as if she was sunbathing when she was attacked, as reported by People.

The area where she was found was thoroughly searched, and her description was cross-checked against thousands of reports of missing women at that time. Despite all the efforts, they were not able to find clues regarding what happened or who the victim could be, per Cape Cod. No one came forward looking for the woman, and although investigators came up with a list of suspects, no one was charged for the crime, as they didn’t have pieces of evidence to tie anyone to the incident.

On October 19, 1974, the Lady of the Dunes was laid to rest at the St. Peter’s Cemetery in Provincetown. Her gravestone reads, “Unidentified Female Body Found Race Point Dunes: July 16, 1974.”
