It's always a sad shame when a workers death involves uncertainty.
I know that Mark's family is deeply concerned what happened to him and why. Thank you fenyxfx for the explanation of what happened.

With 5 deaths at the construction of this casino, it's a wonder that OSHA has NOT shut down this construction. It pains me to wonder what the hell these people are thinking as safety experts.

Wake up OSHA and Las Vegas Officials, you have a severe problem in town.
People are being murdered by the lack of safety in these construction efforts. How many more deaths will you accept before anything is done to correct these egregious occurrences.

My cousin was a great person who would give you the shirt off his back.
I know in my heart that "Shark" took all safety concerns into account and applied them to the best of his abilities in all his jobs. But, there is something just not right here, and we need to find out what, so as to avert anymore deaths.

OSHA is going to have to dig through the contractors and casino's "damage control". I implore the federal, state and city officials to investigate this death and all the others with great expediency and effort.

Rest in peace, Mark!! We'll find out what happened to you, and not rest until we do.
