March 5, 1974. Coconut Grove, Florida. 17-year old Amy Billig phones her father from her home and arranges to meet him at his workplace in order to borrow money to have lunch with friends. Amy is last hitchhiking next to a highway, but she never shows up to meet her father or her friends and is subsequently reported missing. After being informed that Amy was abducted by a gang of bikers, her mother, Susan Billig, spends the next several years attempting to track her down and even encounters a biker who claims to have bought and owned Amy for a time. The Billig family also has to endure two decades’ worth of harassing phone calls from another man who claims to have kidnapped Amy, but even after the caller is identified and arrested, no trace of Amy is ever found. Was Amy Billig actually abducted and held captive by bikers? Was the tormenting caller responsible for Amy’s disappearance? Or could an unknown third party have murdered her instead? This week’s episode of “The Trail Went Cold” chronicles one of the most convoluted missing persons cases we’ve ever covered, which has still not found a conclusive resolution after 45 years.
