We don't know who or the circumstances yet...only the bottom line-the detainee supposedly died on saturday and they claim to be reaching family members before they announce.
Read the little there is here.
A little more information is available here. He was in Camp 5 which means he was being held in solitary and had been a hunger striker until June. They say he was not facing military commission charges-which probably means we have been holding him indefinitely with insufficient evidence to charge him with anything. Sigh.
This seems to be the only way out of Guantanamo for the remaining men.
