Mr King gave police his contact information after discussing the incident. It was unclear if the police ever spoke to Mr Thompson.
Then police received a call from a neighbour and a separate friend on Sunday asking for a wellness check on Mr King as they both were worried about his safety.
Police entered the residence on Sunday afternoon to discover Mr King dead with his body badly slashed and covered in bloody bedding.
A medical examiner suggested Mr King’s injuries were consistent with a large edged weapon, according to CNN, and noted “lacerations to the landlord’s right arm, upper chest and across the neck causing decapitation”.
Police questioned Mr Thompson, who refused to answer any questions or speak. He then wrote on a piece of paper that a “paper in glove compart in Jeep is all you need”, police said.
