The death of Zbigniew Michniewicz in December 2013 was originally treated as a murder after a postmortem revealed evidence of an assault.
Five suspects were arrested on suspicion of murder but nobody was ever charged with causing the death and a medical expert concluded that that the death was caused by drug abuse rather than the injuries to his head.
In June 2014 three men were jailed for plotting to conceal the death of Zbigniew Michniewicz by digging a grave in the back garden of the squat where they all lived in Greenford.
As a result of the medical conclusion in this case we have decided to delete this case from the database.
This is the text of the page before deletion in July 2014:
The body of Zbigniew Michniewicz, 36, was found at a squat in Greenford, west London, on 5 December 2013.
When police called at 251 Greenford Road at around 12.35pm they found a 5ft deep grave had been prepared in the back garden.
Mr Michniewicz was pronounced dead at the scene and an initial postmortem revealed the cause of death was a head injury, including fractures to his eye-socket, cheekbone and jaw.
Detectives said they believed he died a few days after being assaulted at the house on 13 November 2013.
However a pathologist later concluded that Mr Michniewicz died of drug abuse rather than the assault injuries.
Four men aged 20, 20, 40 and 46, and a 17 year-old woman were arrested on suspicion of murder during the investigation.
On 7 March 2014 Grzegorz Roznerski, 40 (17/11/73), of The Crescent, Slough, pleaded guilty to conspiring to prevent the lawful and decent burial of a dead body.
On 5 June 2014 Arkadiusz Majchrazak, 45 [28/5/68], no fixed abode, and Piotr Juszczak, 20 [13/03/93], of Greenford Road, Greenford, were convicted of conspiring to prevent the lawful and decent burial of a dead body after a trial at Isleworth Crown Court.
On 9 June Majchrazak was jailed for nine years, Juszczak was jailed for two years and nine months and Roznerski was jailed for two years and three months.
