We present an unusual murder case by use of repeated administration of organophosphate insecticides. A 49-year-old woman suffering from mental retardation, epileptic fits and acromegaly was poisoned by her husband. At first, her death was considered as a 'sudden and unexpected' natural death. Abdominal abscesses of pancreatic origin found at autopsy were compatible with repeated administration of pesticides with anticholinergic action. In her medical history at least one episode consistent with an organophosphate intoxication was retrieved. Thorough inquiry revealed that the victim had ingested phosphamidon and/or omethoate orally. Organophosphate intoxication should be considered when unexplained neurological symptoms are associated with pancreatic disturbances.
