What is left of a body that what was buried (entombed) for 44 years?

It could be bones and dust, unless it was embalmed. And if the tomb was a nice cool temp, not too dry, not too damp. There could be parts of the flesh that were embalmed enough to survive. If he’s going to be reburied, they might not open the casket. But they could open it up just to see what there was to see.

I don’t think the body cares where it is buried (it not being really conscious).
I think the families of the other people that are buried at the same graveyard care where Franco’s body was buried.
Hence the exhumation an reburial.

The state of the body depends on multiple factors, such as the mass of the person, the geographical location, the amount of moisture in the ground, the temperature, whether he was embalmed or not, etc.
He won’t come out screaming though.

I’m not sure of the embalming skills from 44 years ago but I just want to see it when/if they open the casket!

I worked at a funeral home for a couple years and loved it!

It really all depends on the conditions of the environment the body was entombed in. Many different factors, from the quality of embalming, to the materials the casket is constructed of, how well sealed it is, etc, to the temperature, dampness, etc of the burial site, many factors effect the condition.

The body of Abraham Lincoln, has been moved several times since his death in 1865. His body, however, was well embalmed and contained in a casket made of marble. When it was moved for the final time before being lowered into its current resting place (in his coffin, inside a concrete and steel tomb 10 ft. below the floor level of his mausoleum) his coffin was opened one last time to ensure that his body was still there (that had been attempted thefts of his body before). This was in 1901, some 36 years after his death. It was said that his body was still pretty much wholly intact and fully recognizable as Abraham Lincoln. Although some of his clothing and the American flag that was draped over his body had rotted away.

I assume hair, teeth and skeleton will be present.

I was watching a tv show about the Hunley that civil was submarine, the soldiers were still inside but very decade ,and they needed some dna they went to a cemetery of one of the soldiers relatives and got permission to dig the grave up and get their DNA they were shocked at how well preserved the corpse was except for some old on the dead guys face he looked like he was laid to rest yesterday NOT over a hundred years ago.

The Spanish (Catholics) might have used methods to preserve the body, and above and beyond using chemicals to treat the actual corpse, and they also often used shiny pretty coffins resistant to bugs and the elements, so the body might be fairly intact. Other religions and cultures purposely bury people in a way that is meant to decay. I’ve heard the chemicals used in mummifying help preserve the body. I’m not sure about that.

The body may not care where it is buried but the soul might.
