The FBI announced Ruth Marie Terry was identified as the Lady of the Dunes, a deceased woman found at Race Point Beach in July 1974. Police used investigative genealogy to identify her nearly 50 years after her body was discovered in Provincetown, said Joseph Bonavolonta, a special agent with the Boston bureau.

Terry was born in Tennessee in 1936, Bonavolonta said, and "was a daughter, sister, aunt, wife and mother." She had connections to California, Massachusetts and Michigan.

Many theories about who she was have been put forth over the years, including speculation that she may have been an extra in the 1975 movie "Jaws," which was filmed on Martha’s Vineyard in 1974.
