An inquest into the 2006 overdose death of David Landale, known as ''Pommy Dave'', at the Stuart Flats in Griffith, heard testimony from David Bruce Lunn that he had never made homemade heroin and would not even know how to go about cooking the highly addictive drug.

But in the ACT Supreme Court last week, Lunn was given a suspended sentence after he pleaded guilty to cooking a batch of ''homebake'' between June and September 2007, three months before he made his claims in the Coroner's Court witness box.

Lunn was given a two-month suspended jail sentence last week by ACT Supreme Court Justice Hilary Penfold after he pleaded guilty to using MS Contin pills as the raw material for his homemade heroin.

The court heard that some of the pills had been obtained with prescriptions written by David Prosser, the Belconnen GP who was struck off this year after inappropriately writing scripts for known addicts.

David Landale's naked body was found outside the Stuart Flats public housing complex in Griffith on the morning of November 21, 2006.

Investigators have long believed that the 43-year-old overdose victim had stayed in Lunn's flat on the last night of his life and that Lunn and another man, Neil Hodgson, had not revealed the full extent of their involvement in the death.

While giving evidence to Coroner Peter Dingwall at the inquest in October 2007 into Mr Landale's death, Lunn denied ever having produced home-bake heroin.

The 49-year-old disability pensioner told the coroner he did not use illegal drugs, had never produced narcotics and would not know how to produce homebake. Just one month before he made the claims, detectives who burst into Lunn's flat allege they had found him cooking the drugs on his kitchen stove.
