Pablo Nerida’s body is to be disinterred in order to ascertain if he was poisoned by orders of the Pinochet regime rather than having died from a heart attack while suffering from cancer of the prostate. Suspicions were first voiced by Neruda’s chauffeur and although they are not backed by Neruda’s widow they have not died down. It is unclear if a post mortem will be able to establish definitively how he died. The Wikipedia article on Neruda gives as good background as any and there’s a piece on the decision to disinter in today’s Guardian.
