Identification of Booth's body

[Warren]

I'm confused. If it wasn't Booth who was shot in the barn, then who was it? How did he get there? And who shot him? And why was the barn burned anyway if Booth wasn't inside? Was Booth ever at the farm? Who was Davy paling around with? Did they pay Davy off or threaten him with maybe a hanging if he didn't go along with the fraud? Was he threatened with a medieval hooded torture device if he didn't tow the party line? Killing somebody for grins at that time would have to be a murder because at that point the war in those parts had been over for a couple of weeks. And a body from any recent battles would be far too decomposed to substitute for Booth. Did any one make a missing person report in that time period? Any local gossip about a barroom brawl that went bad, or maybe poltergeist in the neighborhood?
