A man who fatally stabbed a British father-of-two in an Australian town has been declared mentally unfit to stand trial, with a Supreme Court justice ruling he cannot be held criminally responsible.
The Incident
Royce Mallett, a 30-year-old from County Durham, was visiting Albury in New South Wales in July 2024. He was sitting in the driver's seat of a car parked outside the Hume Inn Motel when he was stabbed once in the chest. The attacker, David Summers-Smith, was experiencing symptoms of psychosis at the time, linked to his schizophrenia diagnosis.
Court Proceedings
Summers-Smith pleaded not guilty to murder due to mental impairment. On Tuesday, Supreme Court Justice Dina Yehia determined that while Summers-Smith committed the act, he could not be held criminally responsible. She ordered his indefinite detention in a mental health facility.
Justice Yehia stated: "I am satisfied that the accused has established on a balance of probabilities that at the time he stabbed the deceased, he was suffering from a mental health impairment that had the effect that he did not know that the act was wrong: that is, he could not reason with a moderate degree of sense and composure about whether the act, as perceived by reasonable people, was wrong."
Victim Impact
In a victim impact statement read by Justice Yehia, Mr. Mallett's partner, Caitlin O'Keeffe, described the profound emotional and financial toll on the family. "It affects not just today but every future moment that he should have been part of, and everyday moments that he's already missed," Ms. O'Keefe wrote. The court also heard that Mr. Mallett's father, Roy, has lost interest in hobbies he once shared with his son and struggles to find motivation.
Future Oversight
Summers-Smith's potential recovery will be monitored by the Mental Health Review Tribunal, which has the authority to revise his detention order as circumstances change.
