72 Hours: True Crime

S02:É207 - S02:E207 - Vanished

A beloved small town public school teacher fails to arrive for work for the first time in 30 years, leaving an empty house and a baffled community. Vanished, she seems to have disappeared without a trace. The few clues that are found - a missing chair, a small trace of blood on the floor - fail to shed much light on the mystery, until police turn their attention to a neighbour with a peculiar interest in the case. A neighbour who just happens to work at a landfill.
