What Happened to Janet Chandler?

When 22 year old Janet Chandler was abducted whilst working her Night Shift at the Blue Mill Inn, detectives first believed it to be part of a robbery.

However, when her naked body was found at 1am (2am?) in a wooded area buried in the snow, it would become clear to investigators that foal play was involved. Janet had died of strangulation, with clear evidence she had been bound and gagged for long periods before her death.

Law enforcement would interview hundreds of people over years, chasing dead ends and finding no significant leads.

The case would go cold for nearly 25 years. What happened to Janet Chandler in 1979? And how did what started out as just a documentary project for a film school class, lead to the world finally getting some answers.
