I think my guess has been correct:
Musician accused in quadruple murder told police: "I freed them"
A recent college graduate charged with fatally beating his mother, grandparents and their caretaker with a baseball bat told authorities he "freed them," according to police reports released Friday.
Orion Krause, 22, was naked and covered in mud and cuts when officers found him at a neighbor's house, according to the documents. He allegedly told officers: "I murdered four people." After police wrapped him in a sheet, he began to sing quietly, according to the records.
He is being held without bail at a mental health facility, pending a competency evaluation.
Krause also told a nurse during a medical evaluation that he uses heroin, the records said.
Wayland said Friday that Krause's "mental state at the time of his arrest is an open question."

In my experience, heroin does not make someone kill their mother and grandparents with a baseball bat, and then tell LE that they 'were freed.'
The heroin just exacerbated what was going on emotionally and mentally. JMO

DA: Oberlin grad made "concerning" phone call, killed 4 at grandparents' home
A recent college graduate made a "concerning" phone call before allegedly killing his mother, grandparents and a caregiver at a Massachusetts home Friday, officials said Monday.
"Our investigation reveals that at some point late on Friday afternoon, Mr. Krause made a phone call to an individual that is known to him and made statements that were concerning concerning enough that that individual began to reach out to family members," Ryan said.
Shortly after the phone call, the four victims were apparently attacked. Police then received calls from a neighbor of the grandparents and also from family members that had been contacted by the person Krause called, Ryan said.

I predict he will be declared mentally ill.
