Amy Billig disappeared from Coconut Grove, Florida, on March 5, 1974. She was 17 years old and had just returned home from school when she called her father to ask if she could borrow two dollars so she could meet friends later that day. Her father told her to come to his art gallery to pick up the money. Amy left home and was last seen hitchhiking along Main Highway, something she often did in her neighborhood. She never arrived at her father's office and never met her friends. She has never been seen again. 

Amy was described as an outgoing teenager who enjoyed playing the guitar and flute, reading, writing poetry, and spending time with friends. She had no known reason to run away from home, and investigators quickly began treating her disappearance as suspicious. Shortly after she vanished, her camera was found near the Wildwood exit of the Florida Turnpike, hundreds of miles from where she disappeared. 

The investigation generated thousands of leads over the years. In the days after Amy disappeared, two teenage brothers falsely claimed they had kidnapped her and demanded a ransom. They were later arrested and convicted of extortion after it was determined they had no involvement in her disappearance. As the investigation continued, Amy's family received numerous tips suggesting she had been abducted by members of motorcycle gangs traveling through South Florida, particularly the Outlaws or the Pagans. Some people claimed they had seen Amy with bikers in several states, while others claimed she had been trafficked or murdered. Despite decades of investigation, none of those reports have ever been conclusively verified. 

One of the most heartbreaking parts of the case was the relentless search conducted by Amy's mother, Susan Billig. She spent more than 30 years following leads across the United States and even into Great Britain, determined to find out what happened to her daughter. During that time, she endured years of cruel prank calls from a man who falsely claimed to know Amy's fate and repeatedly tormented the family with graphic stories. The caller, later identified as Henry Johnson Blair, was eventually convicted of making the harassing phone calls, but he was never charged in Amy's disappearance. Despite countless interviews and investigations, there has never been enough evidence to determine exactly what happened to Amy. 

More than 50 years after Amy Billig disappeared, her case remains unsolved. Investigators continue to classify her disappearance as a non-family abduction, but no one has ever been charged and Amy has never been found.
