Mark Frerichs, a contractor from Illinois, poses in Iraq in this undated photo obtained from Twitter that he would include with his resume when job hunting.

The Associated Press has learned that in the days following Frerichs’ capture, Navy commandos raided a village and detained suspected members of the Taliban-linked Haqqani network while the U.S. intelligence community tried to track the cellphones of Frerich and his captors.
