High planning by Floreat gunman suggests brain injury was not a factor
The gunman's careful planning indicated he retained control despite brain injury from strokes.
An inquest heard about Floreat gunman Mark Bombara. Mark Bombara's detailed planning showed he stayed in control.
Bombara killed mother and daughter Jennifer and Gretl Petelczyc while looking for his ex-wife. Neurologist Kevin O'Connor said Bombara took several planned steps.
He gathered guns. He turned off his phone's location tracking.
He wrote a letter. Then he forced his way inside.
This shows careful planning. Bombara had suffered multiple strokes about two weeks before the murders.
They caused brain injury. O'Connor said strokes rarely affect personality.
Post-stroke depression affects about 30 per cent of stroke patients. But he had never seen it lead to murder.
Doctors found a large brain cyst in his scans. It was likely there since birth.
It would not have changed his actions. The planning took place over many days.
This ruled out any sudden loss of control.

Why it mattersThe neurological findings shape how courts judge guilt and responsibility in violent crime cases. Medical conditions are sometimes raised to reduce blame, and these findings matter for how courts view those claims.
