On July 1, 1980, a young mother stood on the side of a remote road in northern San Diego County and watched a stranger drive away with her newborn son. The baby was only 17 days old. His name was Kevin Art Verville Jr., and more than 46 years later, he has never been found. But investigators believe there is a very real possibility that Kevin is still alive, and that he has spent his entire life unaware that the woman who raised him may not have been his biological mother.

Now, the National Center for Missing and Exploited Children and the FBI are asking the public to take another look at Kevin’s case, including a new age-progression image showing what he may look like as an adult. Because somewhere, there may be a 46-year-old man whose entire identity began with a lie.
