Police are still hunting the dealers who supplied heroin to a man who died from an overdose on Christmas morning.

Michael Kirby, 21, died at the Royal Sussex County Hospital in Brighton after being found slumped on the bathroom floor of a pensioner's home.

An inquest at Brighton Magistrates Court heard he and friend Scott Smith spent Christmas Eve at the woman's home.

The pensioner, 67, had bumped into Mr Smith in George Street, Hove, several days before and invited him and Mr Kirby to stay at her home in Portslade.

The inquest heard Mr Kirby, who was born in Lancashire, went into the bathroom on Christmas Day with Mr Smith.

In a statement read by PC Ian Hansford, Mr Smith said the pair had shared a spoonful of heroin.

He left his friend in the bathroom but, when he returned, found him slumped on the floor, blue and unconscious.

He began pumping his chest and told the pensioner to call an ambulance.

Mr Kirby was taken to hospital but died.

The inquest heard Mr Smith had not been seen since an officer took a statement from him at the scene on Christmas Day, when he was still under the influence of heroin.

PC Hansford told the inquest the pensioner could not be called to give evidence because she was too confused.

She had not seemed to know what day it was when police arrived.

There was a hole in her front door through which people could let themselves in and she had even given up her bed to Mr Smith. Investigations into who sold the drugs to Mr Kirby were continuing.

The inquest heard Mr Kirby had been using drugs and alcohol since he was 15.

A post-mortem revealed he died of respiratory failure due to a heroin overdose.

Brighton and Hove coroner Veronica Hamilton Deeley recorded a verdict that Mr Kirby died of an accidental overdose.
