Man declared unfit for murder trial in Australia
28 Apr
Summary
- Man found not guilty of murder due to mental impairment.
- Victim's family questions offender's community presence.
- Offender ordered to indefinite mental health facility.

A man who fatally stabbed a British tourist in Albury, New South Wales, has been declared mentally unfit to stand trial. The accused, David Summers-Smith, pleaded not guilty to murder due to mental impairment.
On July 8, 2024, Royce Mallett was fatally stabbed in the chest by Summers-Smith. The court found that Summers-Smith committed the murder but lacked criminal responsibility due to his diagnosed schizophrenia and symptoms of psychosis.
Psychiatric assessments revealed Summers-Smith had a history of schizophrenia and psychotic symptoms, worsened by the use of methamphetamine and cannabis. He was receiving court-ordered community treatment at the time of the offense but had been self-medicating.
Justice Dina Yehia acknowledged the profound grief of Mallett's family, who questioned how Summers-Smith could be in the community with a treatment-resistant illness. The victim's partner expressed the devastating impact on their children, who would grow up without their father.
Summers-Smith has been ordered to be detained indefinitely in a mental health facility. His case will be subject to periodic reviews by the Mental Health Review Tribunal.
