Simone Ridinger Missing: The Enduring Mystery of Her 1977 Disappearance in Sherborn, MA

On the afternoon of September 2, 1977, seventeen-year-old Simone Stephanie Ridinger finished her shift at the Rainbow Restaurant in Natick, Massachusetts. It was the start of Labor Day weekend, and Simone had plans to hitchhike to Cape Cod, then travel on to Martha’s Vineyard to meet her mother. She never arrived. In the decades since, Simone’s disappearance has become one of Massachusetts’ most persistent and haunting cold cases, raising questions about missing persons, small-town investigations, and the dangers faced by young women in the 1970s.

The Day Simone Ridinger Disappeared

Simone Ridinger was last seen sometime between 12:00 p.m. and 4:00 p.m. on September 2, 1977. She was wearing blue jeans with rips and patches, a white t-shirt, white high-top sneakers, and an assortment of silver jewelry, including distinctive “spoon rings,” bracelets, and turquoise stones. Carrying a gray duffel bag with her waitress uniform inside, Simone told friends she was heading to Martha’s Vineyard for the holiday weekend. Her plan was to hitchhike from Sherborn or Natick to Cape Cod, then catch the ferry to Chappaquiddick Island, where her family had a cottage.

Hitchhiking was a common mode of travel for young people in the 1970s, but it carried risks. Simone’s family and friends never saw her again after she left work that day. She was reported missing when she failed to arrive at her destination.

Initial Investigation: Leads and Uncertainties

The early investigation into Simone’s disappearance was hampered by limited information and the prevailing attitudes of the era. At first, some believed she may have run away or decided to stay elsewhere for the holiday. However, as days passed with no word from Simone, concern grew.

Witness accounts were sparse. Some reports suggested that Simone was last seen in Sherborn, possibly after being dropped off by a friend or a passing motorist. Others mentioned a sighting of her hitchhiking along Route 128 or near Framingham. Police records reference a Sherborn police officer’s daughter who may have given Simone a ride two days prior to her disappearance, but the details are unclear, and the individual later stated she did not recall such an encounter.

Another possible sighting came from an engineer who claimed to have picked up a young woman resembling Simone on September 3, the day after she was last seen at the Rainbow Restaurant. This sighting, if accurate, would suggest Simone made it at least partway to her destination, but no further confirmed sightings have emerged.

Who Was Simone Ridinger?

Simone was described as a free-spirited, artistic teenager with a love for music and the outdoors. She was known for her distinctive personal style and her warmth toward friends and family. Her disappearance left a profound void in the lives of those who knew her, and her family has spent decades searching for answers.

Key Suspect: Eric H. Anderson Jr.

Years after Simone’s disappearance, attention turned to Eric H. Anderson Jr., a convicted killer with a lengthy criminal record and a history of violent assaults on women. Anderson was known to have spent time in the Cape Cod area during the late 1970s—the same region Simone was traveling toward. He later became a suspect in the disappearance of another young woman, Judith Bleiler, who vanished two weeks after Simone, as well as in the 1977 murder of Ruth Masters.

Anderson was eventually convicted of Masters’ murder in 2003 and died in prison. While circumstantial evidence has linked him to Simone’s case, no direct evidence has ever been found tying him to her disappearance. Investigators have not closed the case, and Anderson’s possible involvement remains a subject of speculation.

Challenges in the Case

• Lack of Physical Evidence: No belongings, remains, or clear physical evidence connected to Simone have ever been recovered.
• Time and Memory: As the years passed, memories faded, and potential witnesses moved away or passed on, making it increasingly difficult to reconstruct Simone’s last known movements.
• Era-Specific Attitudes: In the 1970s, missing teenager cases were sometimes dismissed as runaways, delaying urgent investigation.
• Hitchhiking Risks: Simone’s reliance on hitchhiking exposed her to unknown dangers, and tracking her route proved nearly impossible.

Ongoing Search and Recent Developments

Simone Ridinger’s case remains open, and both the Sherborn Police Department and the FBI continue to seek new leads. Advances in forensic technology and renewed public interest in cold cases have brought attention to her story in recent years. Age-progressed images have been released to show what Simone might look like today, and her case is regularly highlighted in missing persons databases and true crime discussions.

Investigators encourage anyone with information—no matter how seemingly minor—to come forward. Even decades-old memories or overlooked details could help solve the mystery.

How the Public Can Help

• If you lived in the Natick, Sherborn, or Cape Cod area in the late 1970s and recall seeing Simone or picking up a hitchhiker matching her description, contact local authorities.
• Share Simone’s story on social media and with true crime communities to keep the case in public view.
• Review old photographs, diaries, or correspondence from that era that might mention Simone or her travel plans.

Remembering Simone: The Human Cost of Unsolved Disappearances
