Man who stabbed father to death with kitchen knife not guilty due to insanity
A 32-year-old Perth man, David Moussa, has been found not guilty of murdering his father and injuring his stepmother due to insanity, with the Supreme Court ruling he acted under delusions caused by psychosis. The court heard that Moussa believed his father had abused him as part of a secret research project, a delusion unsupported by evidence. A psychiatrist testified that a combination of medication and stress likely contributed to his psychotic state at the time of the attack.
