By May 2014, American hostage Peter Kassig was losing hope that he would survive his captivity at the hands of the Islamic State group.
“Dad, I'm paralyzed here. I'm afraid to fight back. Part of me still has hope. Part of me is sure I'm going to die,” he wrote to his father, Ed Kassig, who read the letter from the witness stand Wednesday at the terrorism trial of British national El Shafee Elsheikh.
