Adelaide man found not guilty after stabbing housemate
An Adelaide man has escaped jail time after he stabbed his housemate before pouring accelerant through the home and setting it alight.
Dylan Trethowan, 34, stabbed one of his housemates with a small knife before pouring accelerant throughout the Underdale sharehouse and setting it on fire while other flatmates slept inside in 2021.
The 34-year-old bolted from police and officers were forced to use capsicum spray to subdue him before he was arrested.

Trethowan was found not guilty of arson and nine counts of endangering life due to mental incompetence.
The judge today ruled he must remain under mental health supervision.
The 47-year-old stabbing victim suffered minor injuries.
Trethowan said he was relieved by the judge's decision but apologised outside court for his actions.
"I'm really sorry and I hope everyone landed on their feet and no one was seriously hurt," he said.

The judge however warned if he had been found guilty of the crime, he would have been jailed for more than nine years.
