Sara Georgina Coates, 31, was last seen in early August 2012 while walking with her mother in Stanley Park in Calgary, Alberta. At the time she was travelling through Western Canada in a blue Chevrolet Astro van with her dog and two cats and had a habit of extended, sometimes months-long, absences from family contact, which delayed concern when she did not return.

By autumn 2012 her family grew worried: her van insurance and pet licences were nearing expiry and her bank accounts showed no activity. Her mother reported her missing in December. On October 22, 2013 the blue Chevrolet Astro was found in a secluded area on the Stoney Nakoda Nation near Mînî Thnî; personal items were located in nearby woods but Sara and her animals were not found. Investigators say she had interactions with people in the Mînî Thnî area before she vanished, and searches by police, SAR volunteers and family have continued.

What information might help fill the gaps about Sara’s last known movements and who she met in the Mînî Thnî area?
