If they have all this information on him, then why don't they give the most important details of all - his name and his photo, so he could be discovered, tracked, and caught.
The fact that they don't release this information makes me suspect. It reminds me of all the Osama Bin Laden news reports. One week they say he is dead; the next he is reported alive; then there's reports that he's dying of a disease; then his brother says he's alive and well; then he's confirmed dead; then he's confirmed alive; then he's making a new video...
Good point. Perhaps they wish to keep to themselves the honor of finding him.
