AI-generated summary
Matthew Rosewarne, a 45-year-old man with chronic alcohol use disorder and recent relationship breakdown, was found dead in his shed with a gunshot wound to the neck. Although initially investigated as suicide, the coroner found the investigation fundamentally flawed due to investigative bias. Critical forensic gaps included failure to test alcohol bottles, examine the gun safe, or exclude third-party involvement. Two key anomalies—the safety catch being engaged and the bullet entering the back of the neck (an extremely rare suicide location)—were inadequately investigated. Police failed to remove firearms on 28-29 May despite Ms Staines' warning. The investigation prioritised the suicide hypothesis within the first hour without seeking alternative explanations. The coroner returned an open finding, unable to exclude third-party involvement. Police acknowledged failures and implemented reforms including new firearm investigation protocols and bias training.
