I worked at the Beau Rivage casino in Biloxi, MS for a while when it was under construction. As I was leaving one night, I noticed a bunch of people standing around a crowd yelling something. I walked over to see what was going on and there was a man lying in a concrete vat (it looked like a small in-ground swimming pool). Apparently he was working a few stories up. Well, the I-beams had thin, plastic covers that ran across them. What purpose that serves, I'm not sure, but I guess the plastic blocked his view of the beam and he fell right off and into that concrete vat. His head was cracked open and the vat was covered in blood and the poor guy was mumbling for help. An ambulance picked him up a few minutes later, but he was pronounced dead on arrival.
