The "Sons of Anarchy" actor suspected of killing his landlord before falling to his death on Wednesday had drug issues, mental health problems and was a threat, his probation report said last spring.
The May 17 report says that Johnny Lewis, 28, "suffers from some form of chemical dependency, mental health issue and a lack of permanent housing. Given this, (Lewis) will continue to be a threat to any community he may reside."
Police are seeking to understand what may have sparked the rampage that led to the death of Katherine Davis, 81.
She died from "blunt head trauma and strangulation," according to preliminary findings from the autopsy conducted Thursday, the Los Angeles County Coroner's office said.
Lewis was arrested twice in February on burglary and battery charges in Santa Monica, according to records obtained by CNN.
But Lewis' lawyer, Jonathan Mandel, said Friday that he had not considered his client a threat to anyone. "The behavior with me was fine," he said. "What was known in May about Johnny was that he had two fairly minor offenses -- which were, fortunately, not serious. And he did have a diagnosis, eventually, of chemically induced psychosis."
Mandel, who first represented Lewis in April, said he never would have predicted Lewis' involvement in a killing and had not suspected he was taking drugs.
"From April until August or September, he was probably using no drugs at all," he said. "He was incarcerated for a couple of months and then he went to a treatment facility."
Though Lewis did appear, at times, to be delusional, "I never got the sense, when I was representing him, that he was an addict. I did think that he had severe mental problems."
Police suspect drugs may have been involved, but "we don't have any hard evidence that says he was on anything right now," LAPD Commander Andrew Smith said Thursday.
