I Digitally Recreate Faces To Solve Cold Case Murders ─ VICE

Web sleuths are private citizens with no formal training who spend their time online trying to solve cold cases and to identify John and Jane Does.

Carl Koppelman is a renowned web sleuth who has assisted in identifying 8 victims who identities were unknown.

Using an internet forum called Web Sleuths, Carl and others are responsible for providing valuable context to cases that would otherwise be left cold. These sleuths often take on pet projects that they'll work on for years at a time, searching for an answer to a question most people forgot long ago.
