There was some speculation about the possibility that D.P. dissolved the body in some chemical.
Some research showed it takes about 3 days to dissolve the body in this method (ties in nice with the 3 day head clearing trip).
If this is the case, he would not have dug a grave but rather a hole to pour the remaining solution.
The barrel could be or not be part of the burial site....
Closeobserver, I suspect one of the reasons for this speculation is because of what Stacy once told her sister. Something to the effect, "If I ever disappear you need to find me with in 2 days".
How strange a thing to be saying unless Stacy had heard something or been threatened by those words to make her concerned.
Another reason is Why so many 50 gallon barrels of 'pool' chemicals in the garage. Anyone owning a pool knows you don't need chemicals in 50 barrels to treat pool water.
The following is some information which I wonder IF DP had read about or heard about that happened between 1944-1948.
There was a British killer, by the name John George Haig who was called
"The Acid Bath Murderer," He came up with an idea on how to commit perfect murders.
To make a long story short.
In 1948 Haigh killed his lady friend after having her come to his workshop.
He placed her body in a 45-gallon oil drum, and filled the drum with
sulfruic acid, left it to stand for 2 days until the body had
disintegrated and swilled out the residue across his yard outside.
Sadly, This reminded me of the words Stacy used,"find me in Two days".
