It isn’t clear why Camfield killed Doss.
Camfield sent a text to someone after the slaying, saying he killed Camfield for his truck, according to DuBoise. However, during a later interview with police, Camfield didn’t give a reason, prosecutors said.
“We believe justice in this case required that the defendant never be released back into the public,” Assistant District Attorney Nikki Rhodes said. “There were many facts about this murder that were disturbing. However, deeper investigation into the defendant’s mental health history explained some of the unusual facts investigators found at the crime scene. Other details of the murder are simply inexplicable. Despite some history of mental illness and drug use, the defendant acknowledged he knew what he was doing at the time of the crime when he entered his guilty plea.”
The district attorney’s investigation reportedly revealed that Camfield had been involved in a couple of physical confrontations that had not been reported to police though he had no significant criminal history and no documented history of violence.
Officials said Camfield was homeless and living in the basement of the former Weatherford ISD administration building, which had been vacant for some time, when it was destroyed in a fire about a month prior to the killing.
The cause of that fire remains undetermined but it is believed to have started in the basement area.
Camfield began exhibiting schizophrenia after he began using heroin sometime prior to June 2010, according to Rhodes, and Weatherford law enforcement officers who interacted with Camfield on a couple of occasions in 2012 noted that Camfield appeared to have some mental health issues.
However, his defense team told the judge they believed him to be competent to stand trial and did not raise an insanity defense.
Prosecutors also believe drugs played a role in the slaying based on Camfield’s statements.
