They wore loincloths made of bark and used a homemade axe to chop down trees for firewood. They fed on corn that they had grown, plus fruits and cassava roots from the jungle. Inside their treehouse home, five metres in the air, the pair kept a stash of arrows for hunting and knives for killing animals. After they were returned back to rest of civilization by travelers, they had almost completely lost the ability to speak a language. The Vietnamese district authorities have confirmed that the father Ho Van Thanh once lived a normal life with his family in the commune’s Tra Kem hamlet. They suggested that he was probably driven by shock when he took his young son and ran into the jungle after the mine explosion wiped out the rest of their family.
