Maria Marlies Jansen, 76, disappeared from her Pacifica, California home in the Park Pacifica neighborhood on July 25, 2012. She was last seen about 5:30 p.m.; her husband was the last person known to have been with her. Jansen had Alzheimer’s disease, and her disappearance was classified high-risk.

She is described as 5 feet 5 inches, about 100 pounds, with gray hair and brown eyes. At the time she went missing she wore green pants, yellow clogs, a shirt of unknown color and a white gold wedding ring with diamonds. Extensive searches by authorities and volunteers produced no significant clues, and several leads and area searches did not locate her.

The Pacifica Police Department is the primary agency handling the case and asks anyone with information to come forward. Does anyone in the community remember seeing Marlies in late July 2012 or have information that could help locate her?
