Dianne Jane Carlson, 29, of Petaluma, California, was last seen at her home on August 14, 1976. She is 5 feet 4 inches tall, about 125 pounds, with blonde hair and blue eyes. On the day she vanished she wore a brown jacket and white pants. Her maiden name is Jensen.

Her disappearance is classified as an endangered missing person case and investigators have described the circumstances as suspicious. Very few details are available publicly; she was last seen at her residence and has not been heard from since. At some point after she disappeared her husband petitioned to administer her estate, a development that adds to the unresolved questions in the case.

Does anyone from Petaluma or who knew Dianne Jensen Carlson have information that could help explain what happened that day?
