Satan?

Gruesome:

• Mixed martial arts fighter Jarrod Wyatt is charged with the murder of his sparring partner, Taylor Powell.
  
  Wyatt, 26, allegedly cut an 18-inch hole in Powell's chest and removed his heart, tongue and most of his face.
  
  Wyatt reportedly was under the influence of psychedelic drugs and had been increasingly focused on Doomsday scenarios leading up to the March 21st murder.
  
  Del Norte County Police Sgt. Elwood Lee responded to the scene and said that Wyatt told him "Satan was in that dude."

We were under the impression that the Dark Prince had taken up residence in Shortshanks' body and that his "speaking in tongues" was a result of Daley's feeble struggles to reassert control over his body.

But this guy seems to be a better candidate for demonic possession.
