Summary based on the NamUs case record (MP26658) and 8 other sources
Nancy MacDuckston, a 52-year-old woman from Belmont, California, was last seen on the morning of August 11, 2003. She informed family and friends that she was taking a day trip to Davenport, a coastal town she frequented, located in Santa Cruz County. She was spotted shopping and mailing postcards in Davenport and later that afternoon, was seen having dinner with an unidentified man at a local restaurant. This man, described as Asian or Polynesian with salt-and-pepper hair, has never been identified but is not considered a suspect. He was seen with MacDuckston in what appeared to be a friendly or romantic interaction.

Later that day, her tan 2001 Mazda MPV minivan was found abandoned along Highway 1, near a cliff by one of her favorite coastal spots. Personal belongings, including a chair, blanket, book, and her bright pink sun hat, were found nearby, suggesting she may have been relaxing at the beach. Despite thorough searches, no trace of her was found, though a search dog tracked her scent to the edge of a cliff. This led to speculation that she might have fallen or taken her own life, though she had no known history of mental health issues.

MacDuckston was a beloved teacher and family-oriented woman with no clear signs of distress leading up to her disappearance. While some believe she may have voluntarily disappeared or met with an accident, her case remains unsolved.
