AI-generated summary

Karen Louise Richards, 41 years old, died from mixed drug and alcohol toxicity on 11 January 2014. She had consumed heroin (evidenced by 6-MAM metabolite), alcohol, benzodiazepines, and other prescription medications. Her boyfriend Angelo D'Amario discovered her unconscious around 10:10-10:40 pm but delayed calling emergency services for 1-1.5 hours until 11:44 pm. During the 000 call, he sounded calm and unurgent. He did not initiate CPR until instructed by the operator and required repeated prompting to continue. The coroner found D'Amario's delay in seeking help and failure to promptly administer first aid deplorable, particularly given he was the only person present. The coroner noted D'Amario likely supplied the heroin and was dishonest throughout police interviews and the inquest. Key clinical lessons: rapid recognition of altered consciousness and immediate emergency response are critical; drug users and their contacts require education on overdose recognition and first aid; delay in treatment initiation reduces survival chances in opioid toxicity.
