When you search the Farm you find several things. You find that the civilians are very hostile towards you and will do nothing to help you. They resent you killing the soldiers in their farm and resent even more you stealing all of their possessions.
Out in the hay shed you find a walkman with no batteries. Using the batteries you found earlier you start it up, after all a little music always helps your morale. It turns out to be a taped message from Pepi Cortez.
"Hola Amigos, it is me. You know who I am. If this is el army listening, it isn't me. Anyway I spoke to the civilians here and they were no use except that the little boy said he saw a muy poco girl being led away by el soldiers on de road to de north. Dat is where I be going now. This is Pepi, ah I mean Pierre, Pierre… ah, Clinton, singing off for now. To find de next message tink of rain."
