Family friend Todd Geiler on Sunday said that the parents of Kayla Jean Mueller, of Prescott, Arizona, are asking the nation and the world to pray for her return.
The Islamic State group said Mueller died in a Jordanian airstrike. The government of Jordan dismissed the statement as propaganda.
US officials say they have not seen any evidence to corroborate the report.
Mueller is the only known remaining US hostage held by the Islamic State group. She was taken hostage in August 2013 while leaving a hospital in Syria.
