Hailey, Idaho (CNN) -- No one here knew exactly where he was or what he was going through, but this tiny city in Idaho never forgot about Sgt. Bowe Bergdahl. Yellow balloons and American flags line the sidewalks of Hailey, population 8,000. Residents planted one tree for each of the five years Bergdahl was held captive in Afghanistan. Now, uncertainty has given way to elation as the Army sergeant has been released from his captors -- in exchange for freeing five Taliban members held at Guantanamo Bay. "There were times where we wondered, but (parents) Jani and Bob Bergdahl never once gave up faith that their son was coming home to them," family friend Stefanie O'Neill said.

Bergdahl's condition on Monday was stable, and he was "receiving treatment for conditions that require hospitalization," a
American defense official told CNN.
