He had heard voices he believed were from another dimension. He had felt there was a demonic force pressing on him.
He had at times believed his father was the devil.

Walsh once bought a length of rope during a bout of severe depression but didn't use it.
He had been admitted to psychiatric hospitals several times, once after a fist-fight with his father. But he was later released and returned to university.
He also had a history of extensive drug-taking and used magic mushrooms and cannabis.
He was aware he had mental health issues but he chose to continue to self-medicate.
Shortly before his death, Phil Walsh received a chilling text message from his son.

Ms Walsh said there was a lack of information available to families like hers, calling for increased mental health research and awareness.
"We now all live with the devastating consequences of a mental illness that was not understood," she said.
One psychologist in the case believed Walsh had been unwell for far longer than those around him realised and that his use of drugs masked this.
Justice Anne Bampton accepted the diagnosis of schizophrenia that three medical reports had come to following Walsh's arrest.
"I find he was suffering a psychotic episode as a result of schizophrenia, which at the time of the conduct was undiagnosed and untreated," she said.
But she accepted forensic reports that found Walsh was not affected by drugs at the time.
Walsh wore a white shirt with a light-blue tie, and his dark hair was brushed back when he appeared in court by video link.
Justice Bampton fixed a term of supervision equivalent to life imprisonment.
The Adelaide Football Club chose not to comment.
