Case 0091 - Evidence 0004 is an interview with one of the farmers whose flock sheep was affected by "The Pattern", which was shown in the previous evidence video.
Here is a transcript of the video:
Interviewer: Tell me about this picture of your sheep.
Farmer: Well, I’m not sure really, the sheep were going about there business, then I heard an earthquake or something underground.
Interviewer: And then what did you see?
Farmer: I’m not sure. The sheep didn’t make a sound, so I looked out of the kitchen window and saw them walking around in a circle... a perfect circle... like something was... controlling them. I've never seen anything like it.
UPDATE: Here is the audio of the strange voice at the end. I tried reversing the audio, but that didn't help. It really sounds like it is possibly a different language...?
