Quick Summary

A WA Police constable testified during an inquest that he viewed double murderer Mark Bombara as a "nice man" during a police escort to the suspect's Mosman Park home on April 1, 2024. The officer admitted he failed to prioritize Bombara's firearms and ammunition despite the family's safety concerns, noting that he spent an hour chatting about the suspect's 54-foot boat and property. This report focuses on the officer's testimony regarding his own lack of suspicion and the "grooming" of police by Bombara, who later ranted about the police visit in a suicide note.
