The trial was listed for three months due to complexities arising from the inability to scientifically ascertain the cause of death; the need to call a large number of witnesses and because there was a deep pool of known and unknown suspects who had to be excluded as being responsible for R’s death. H also made a substantial application to stay the indictment as an abuse of process on the grounds of delay and difficulties with the investigation causing him not to have been identified as a suspect and arrested until 2014. The application for a stay was successfully opposed. At trial, H pleaded guilty to manslaughter and the other offences and was sentenced to 18 years’ imprisonment.
