Peter Kassig first went to the Middle East as a U.S. soldier and
returned as a medical worker, feeling compelled to help victims of war.
"We each get one life and
that's it. We get one shot at this and we don't get any do-overs, and
for me, it was time to put up or shut up," he said in a 2012 interview
with CNN.
Now Kassig, 26, is being held hostage by ISIS.
His life was threatened Friday in an ISIS video that showed the apparent beheading of British aid worker Alan Henning.
In a statement Friday,
Kassig's parents, Ed and Paula Kassig of Indianapolis confirmed that he
was being held hostage by ISIS but provided no other details. They had
maintained silence about his capture since he was taken hostage in 2013.
"The Kassig family
extends our concern for the family of Alan Henning," Kassig's parents
said. "We ask everyone around the world to pray for the Henning family,
for our son, and for the release of all innocent people being held
hostage in the Middle East and around the globe."
