New feral child case

Actually, feral adult, I suppose: she is 19 years old now. This from the BBC:
A Cambodian girl who disappeared aged eight has been found after reportedly living wild in the jungle for 19 years.
Rochom P'ngieng's father says he has identified her through scars but she cannot speak any intelligible language.
...

Sal Lou, a village policeman, said he recognised the woman as his daughter from a scar on her right arm.
He said: "When I saw her, she was naked and walking in a bending-forward position like a monkey... She was bare bones.
