Mark Frerichs is a 58-year-old American civilian contractor and a former Navy diver. He was abducted in Kabul last year, right around the time the Trump administration was finalizing the deal that would end the United States’s troop presence in Afghanistan after 20 years.

His initial captors reportedly turned him over to the shadowy Haqqani network, a group on the State Department’s list of terrorist organizations, and it’s believed that the Taliban took custody of him sometime last year.
