Summary based on the NamUs case record (MP18174) and 4 other sources
Shannon Eileen Staal, aged 36, was last seen at her home in Menifee Valley, Riverside County, California, on July 10, 1979. She has not been heard from since. At the time of her disappearance, Shannon was described as a white female, 5'2" tall, weighing 125 pounds, with blonde hair and blue eyes. She had several distinguishing features, including healed fractures in her nose and right foot, and scars on her left middle finger and between the toes of her right foot. She also had a full dental plate and had previously given birth. She may have used the last name Hickey or Hickory.

Very few details are available about the circumstances surrounding her disappearance. Despite efforts by the Riverside County Sheriff's Department, Shannon's case remains unsolved, and no significant leads have surfaced over the decades. Investigators continue to search for answers and encourage anyone with information to contact local authorities.
