This unexpected situation left the three hopeful CIA agents deeply disappointed, so they called over the CIA informant in the area to question him. It was the intelligence from this local informant that informed the CIA of a Chinese young man being treated at this temporary hospital.
More than twenty days ago, before US fighter jets, army troops, and senior CIA agents were killed, they had all sent back some intelligence. Although incomplete, these reports all mentioned a Chinese young man. So when the three CIA agents learned that the temporary hospital near the crime scene was treating a Chinese young man, they calculated the timing and suspected that this individual was likely the Chinese person responsible for eliminating a large number of their own nationals and equipment.
