I wonder if he could have had anything to do with the disappearance of John and Elizabeth Calvert in 2008? They were missing from their vacation home in Hilton Head. They were suspected to have been killed by a man who committed suicide but as far as I can tell they never foudn their bodies and never found the suspected murder weapon--a gun missing from their home.

A few things of thing of note: The Calverts had a yacht named the Yellow Jacket and TK had posted about bushhogging his beach area and hoping the yellow jackets didn't come out to play on the same day as one of the Coxie's relatives posted a plea to fb looking for them ...granted that post was years later fromt he time the Calverts went missing...but he may have been thinking of prior victims while posting about more recent ones (the Coxies) or he might have been burying/moving the Coxies that day.
Elizabeth Calvert had a pilot's license and they owned a private plane
The last man to see them alive was an accountant for a realty company called
The Club Group. He committed suicide and confessed in his suicide not that he stole money from the Calverts.
