By witness they meant watch the body being put in the oven and it's door being closed. Not the same thing.
There's an abandoned nut house a few miles south of here with some ATV trails nearby.
In the corner of the property there's some old maintenance buildings with pumps and air compressors & a small sewage treatment plant with trees growing in it and stuff.
There was a big cast iron crematorium big enough to roast an elephant in, with a smoke stack that's still standing. Lots of rumors & conspiracy theories about that.
My neighbor's brother stole it for scrap iron about 5 years ago. Said it took him 2 days to cut it up and haul it to the recycling place. I bet he spent more on gasoline, oxygen and acetylene than he got from the scrap metal.
