Isn't it from the song: "Hay Una Mujer"

The chorus is:

Hay una mujer desaparecida, Hay una mujer desaparecida
En Chile, en Chile, en Chile.
And the junta, and the junta knows
And the junta knows where she is
And the junta knows where they are hiding her; she's dying--
Hay una mujer desaparecida, Hay una mujer desaparecida
En Chile, en Chile, en Chile.
