These test results are necessary before anyone is charged. The investigators will need to rule out some other possible causes of death before recommending that somebody be charged with causing that death. To not do so would invite defence lawyers to criticse, for a jury's benefit, the conduct of the investigation. If they are indeed waitexpecting a null report, there will be nothing to report or to release. Even if police suspected the involvement of drugs in the death, these tests may not necessarily be conclusive or even useful, depending on how long before death the drugs were ingested and the particular metabolites involved (if any). Furthermore, the John Tonge Centre is notoriously under resourced.
Once charges are laid, whcih constitute the commencement of criminal proceedings, the forum owners should consider the nature and extent of the discussion on the forum until those proceedings are completed.
