Hertfordshire Police have issued a statement on the preliminary post mortem results:
There is no evidence of third party involvement and the death is non suspicious. Further toxicology results are now awaited and there is an on-going examination of health problems identified at the post mortem.
Please note, toxicology reports can take some weeks and we cannot make any further comments at on the post mortem, including the problems at this time
If I was the family I would call in an independent pathologist quickly. We all remember the first pathology report on Ian Tomlinson. Sean Hoare may indeed have died from natural causes, though it is unusual with modern communications for someone in their forties to do that with a suddenness that precludes a call for assistance. But unfortunately, the lies police told about Jean Charles De Menezes, the far too convenient first post mortem on Ian Tomlinson, and the lack of any inquest on David Kelly, means that it is no longer possible in this country simply to accept the word of the authorities on such things.
