Angela Caroline Hartmann, 27, was last seen on August 22, 1983, while traveling across Canada. She had been moving between Ottawa, Thunder Bay, and Calgary that summer and was due to start at Trent University in Peterborough in September, but never arrived. The last confirmed sighting was in Ottawa; she sent postcards home during the trip and her father was receiving mail in San Francisco, yet the disappearance was reported in San Francisco, which added procedural complexity.

Angela was described as 5 feet 2 inches tall, 115 pounds, with blonde hair and brown eyes. Little information or public developments have emerged since her disappearance and the case remains open.

If anyone remembers seeing Angela in Ottawa or along the route between Ottawa, Thunder Bay, and Calgary in August 1983, please come forward with any information.
