The father of a 22-year-old American man who went missing in Germany over a week ago says he is "terrified" by his son's disappearance.
Devon Hollahan, who had been teaching English in Prague since July, disappeared after attending a concert in Frankfurt on Nov. 3.
His father, Jeff Hollahan of Scottsdale, Arizona, said after arriving Monday in Frankfurt that "we have heard nothing since that time ... I'm anxious to talk with the police and the U.S. governmental services here."
The U.S. consulate in Frankfurt and local police are both involved in the search for Hollahan.
