Alexanda Kotey and El Shafee Elsheikh were the two remaining members still at large of an ISIS group known as "The Beatles" because of their British accents. They tortured and beheaded more than 24 hostages, including Foley.
French journalist, Nicolas Henin, was in captivity with Foley. The two became close in their darkest time. But after ten months, Henin was freed. He still has nightmares about the torment they went through.
"I don't like to give details about the treatment we received," Henin says. "There were more than two dozen western hostages. I was one. Some of us ave been extremely tortured."
Henin says he saw the mug shots of Kotey and Elsheikh, and immediately recognized them as his captors. To honor Foley and others who were killed, Henin hopes "Kotey and Elsheikh are put on trial in England, and shown what real justice is."
