The FBI Files

In September 1997, a team of masked gunmen robbed an armored car facility in Los Angeles, and made off with $18.9 million, the largest takeover heist in U.S. history. An employee believed she recognized the voice of one of the robbers, and FBI agents began conducting surveillance on a former employee of the facility. With only one piece of physical evidence, a fragment of a vehicle taillight, authorities hoped to connect him to the crime, and locate his accomplices.
