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." Lee added that Wyatt also said he'd cooked the body parts in a wood stove because he thought Powell was still alive.
Wyatt currently faces a first-degree murder charge.
