Well, unfortunately I just heard that the worst has occurred, and according to the freshest article at the New York Times, it is confirmed. Hondros did not live long after sustaining major brain tissue loss during the attack. He survived in a coma for a few hours despite this, hence the initial confusion. Condolences to his family, friends, and co-workers, who as far as I can tell greatly admired and respected him.
At least there is some positive news; the two other journalists with them, Guy Martin and Christopher Brown, survived.
It turns out that Liohn was not injured, as initially reported, but reported the story from the triage center.
