The mother of American journalist Austin Tice, who is believed to be held in Syria, was joyful when another U.S. citizen was found last week following the collapse of the Assad regime.

Tice was taken by Bashar al-Assad’s government more than a dozen years ago, and the U.S. government has been unable to locate him in the week since Assad fled to Russia. However, Tice’s family is hopeful they will get to see their son again, given Syria’s political change.
