This September, Reveal takes us inside America’s coldest cases. There are more than 10,000 John and Jane Does in the U.S. – unidentified and unclaimed bodies languishing in limbo for years, sometimes for decades. In the episode, we crisscross the nation tracing John and Jane Doe cases, showing why so many bodies remain unidentified despite new and powerful forensic tools. Often the job of solving these cases is taken up by amateur web sleuths. Reveal’s award-winning data team has come together to make matching those lost and found easier.
