The parents of an Arizona woman who was killed in Syria are hoping two captive ISIS fighters can give them answers.
Kayla Mueller worked for a humanitarian group in Turkey in 2013 and was kidnapped and killed in Syria. She was reportedly enslaved by ISIS for more than a year.
Two ISIS fighters who have been taken into custody by Syrian Kurdish forces are believed to have tortured Mueller.
Her parents, Marsha and Carl Mueller, told the "Arizona Republic" they want the terrorists to be kept alive. They've published a plea asking that the two terrorists be tried in the U.S. or in a court of international justice, and are hoping the men can lead them to their daughter's remains.
