I am not registered at the Chicago Tribune, so I couldn't read the article there.
There is another one, which presumably has similar info (?)
Imam once informed on militants for CIA
Maybe it was never a kidnapping, but a way to give cover to the Imam.
I recall reading in earlier articles, that eventually he called home from Turkey (?). Obviously if the CIA really had kidnapped him, they wouldn't have let him loose.
The link was active, now it's not...DARN!
I guess others can use BUGMENOT.COM
