A 22-year-old Southampton man lay on the floor for 12 hours before his friend realised he was dead. 

Michael Turpin, of Ellwood Avenue in Thornhill, had been clean and sober before taking heroin in October with a man he met when living in a Southampton hostel five months previously. 

The pair had not been in contact but in a statement David MacIntosh said Mr Turpin called him and asked to visit him at his home in Cranbury Avenue. 

The inquest heard they shared a “£10 deal” of heroin, before Mr Turpin injected himself with more of the drug. 

Mr MacIntosh said they fell asleep. He had been smoking and talking with friends in the same room as Mr Turpin, who was staying on the bedroom floor, on October 19. 

He said he heard him snoring at around 2pm but when he tried to wake him at around 1am on October 20 he was dead. 

PC Jason Cavett, of Portswood Police Station, said he thought the length of time he was left on the floor was “strange” but the death was not treated as suspicious. 

The inquest heard Mr Turpin died from lung and heart problems, caused by taking a dose of heroin in the fatal range. 

Senior coroner for central Hampshire, Grahame Short, said he believed the overdose was not deliberate and ruled a verdict of drug-related death.
