A cursory search indicates that he worked independently for the Global Post.
I can’t remember details on this. I hope Mr. Foley rests in peace.
“James Foley, a freelance journalist who contributed to the GlobalPost, NBC News and the PBS NewsHour was reportedly killed this week by his Islamic State Group captors. Foley has been missing since November of 2012, when he was abducted in Syria. GlobalPost led the efforts to keep track of Foley after his abduction, and suspected that Foley was being held in a Syrian government detention center.”

Interesting that it was thought he was being held by the Syrian government. What that tells me is that US journalists know nothing about what is happening in Syria and have no reliable sources.
ISIS is apparently threatening the life of another held journalist, Steven Soltoff.
