Judge for yourselves - I think all the comment that is required is this extract of the summary from the scientific paper on Richards autopsy written by amongst others a
world expert in neuro-toxology:
We report here the case of a 43-year old airline pilot who presented with neurological deficits and other symptoms. The pilot died without regaining good health. In vivo blood had been collected ante mortem. Analysis of the serum confirmed grossly elevated levels of serum autoantibody biomarkers for neuronal cell degeneration compared with a control group. At autopsy, various tissues underwent histopathological assessment. Brain and spinal tissues exhibited axonal degeneration and demyelination. Peripheral nerves showed T-lymphocyte infiltration and demyelination. T-lymphocytes had infiltrated the heart muscle tissue. The post-mortem tests and pathological examination of the nervous system confirmed the autoantibody biomarker results. Differential diagnosis showed that the work environment, clinical condition, histopathology and serum biomarkers for nervous system injury are consistent with organophosphate-induced neurotoxicity. The results also indicated that the inferred exposure to organophosphates sensitized the nervous system and heart tissue towards further injury.
