In a bronze lined catafalque seven? feet down under that slab.
A bronze-lined vault. The vault and the casket, together, weigh 4,000 pounds, and required a small crane to lift the vault out of the ground, place the casket in it, place the top of the vault over the base, seal it, and lower it back into the ground.
According to new stories, the grave was covered at 3 am, Pacific time, on Saturday morning.
