title: Payment deferred: strychnine poisoning in Nicaragua 65 years ago.
abstract: BACKGROUND
  In 1933 in Leon, Nicaragua, a 22-year-old woman died after an acute convulsive illness in which she experienced trismus, opisthotonos, and hyperpyrexia. Three years later her husband, Oliverio Castaneda, was convicted of her murder and that of 2 other people in the same city.
  
  
  METHODS
  We went to Nicaragua to investigate documents involved with that case and evaluate whether the verdict of murder by strychnine was substantiated by the data. We present the results of the investigation and provide information about the practice of medicine, pharmacy, and toxicology early in this century.
  
  
  RESULTS
  The clinical picture in all 3 cases suggests strychnine poisoning. The clinical, toxicological, and circumstantial evidence is strong and implicates Castaneda as a murderer and strychnine as the weapon.
  
  
  CONCLUSIONS
  We conclude that Oliverio Castaneda was the probable perpetrator of three 1933 strychnine murders in Leon and that he may have previously used strychnine to kill others in Nicaragua and neighboring countries.
