AI-generated summary
Between 16-17 October 2016, Fernando Manrique deliberately introduced carbon monoxide gas into the family home in Davidson, NSW, killing his wife Maria and children Elisa (11) and Martin (10) while they slept. The coroner found three victims died without knowledge while Fernando died by suicide. Fernando had obtained commercial carbon monoxide cylinders through deception, had them delivered to a third party's residence, and constructed a piping system to introduce lethal gas. The deaths were triggered by marital breakdown and Fernando's financial stress, combined with his inability to accept Maria's decision to end the relationship. The coroner found this constituted family violence. The case highlighted inadequate regulation of commercial carbon monoxide supply; Fernando exploited ease of online ordering, use of business identity, and residential delivery practices. The coroner recommended addition of carbon monoxide to the Poisons Standard and enhanced supplier controls including driver training.
