AI-generated summary

Three family members died on 1 February 2015 when a car was deliberately driven into a tree: Darren Milne (42), his wife Susana Estevez Castillo (39, pregnant), and their son Liam (11). Darren, an electrical engineer, premeditated the act with extensive planning including reconnaissance video, iPad notes detailing 'stage 2' of a plan, and engineering of an incendiary device hidden in the engine bay. He had been treated for depression but discontinued psychological care in August 2014. The family's two boys had Fragile X Syndrome and autism; concerns about their care appear to have driven the act. The coroner found these deaths deliberately caused and preventable. Benjamin, the younger son, survived with permanent injuries. The coroner emphasised availability of mental health support services.
