Erlier on at about 11 pm i was on my way up this mountain to pick up my brother from his friends , and on the way we saw about 4 police cars outside this farm and they asked us to turn round and go round the other way because the road was blocked off . So my sister asked them what s going on and they said that a group of kids have come up the mountain and have been shooting cows and cutting their body off , leaving their head and legs behind for meat . I thought this was sick so we turned around and drove back the way that we came and i saw a cows head hanging from the fence with blood all over it . I felt so sick and now i ca nt seem to stop thinking about this .
