Summary based on the NamUs case record (MP97264) and 2 other sources
Dianne Jane Carlson, a 29-year-old woman from Petaluma, California, was last seen on August 14, 1976, at her home. She was described as being 5'4" tall, weighing 125 pounds, with blonde hair and blue eyes. On the day of her disappearance, she was wearing a brown jacket and white pants. Her maiden name is Jensen.

Dianne’s case is classified as an endangered missing person case, and very few details are available about the circumstances surrounding her disappearance. She was last seen at her residence, but she has not been heard from since that day. Investigators have labeled the case suspicious, but no further developments or information have been publicly released.

At the time of her disappearance, Dianne’s husband later petitioned to administer her estate, further raising questions about the circumstances. Her case remains unsolved, and authorities continue to seek any leads or information that could help resolve the mystery of what happened to her.
