Officers discovered Mr Smith's body in a wheelie bin behind nearby derelict properties. Dr Lyall said it was not possible to determine whether Mr Smith had drowned and that drowning could neither be proved nor ruled out. Recording a drug-related death conclusion, the coroner said Mr Smith died after taking illicit and sedative drugs which caused respiratory failure. Earlier this year, three people were jailed over the deaths of Mr Greener and Mrs Jackson. Owens, 46, was sentenced to 13 years and six months after being convicted of the manslaughter of Mr Greener and Mrs Jackson.
