AI-generated summary

A 43-year-old man died from methylamphetamine and heroin toxicity while on home detention bail. He had a complex psychiatric history including depression, psychosis, PTSD, and polysubstance use disorder, with previous suicide attempts and admissions. He was engaged with mental health and addiction services but disengaged from treatment after May 2021, with only phone contact thereafter. He tested positive for amphetamine in August 2022, breaching bail conditions. The night before his death, he messaged his ex-partner with ambiguous text suggesting possible suicidal intent, though his grandmother spoke to him shortly before and he appeared positive about a Father's Day visit. He was found dead the following morning with drug paraphernalia and a syringe in hand. The coroner could not determine if the overdose was intentional or accidental.
