Background information and notes

The letter from Trudy Pomeranski addressed to the New York Ledger.

  • The episode title, "Poison", refers to the method of murder used by this episode's killer to achieve her goals. This title is also used for the Law & Order: Special Victims Unit season five episode "Poison (SVU)".
  • A key element of this episode seems to have been based on the Excedrin tampering murders of 1986, carried out by Stella Nickell and the 1982 Chicago Tylenol murders, for which the perpetrator was never caught. Trudy Pomeranski tampered with several bottles of the fictional painkiller "Necedrol" in order to murder her husband. Similarly to Stella Nickell, she did it for insurance money with which to open a children's clothing store.
  • The address on the envelope sent to the New York Ledger is 208 South Street, in ZIP code 10001. However the real address should be in ZIP code 10002. NY 10001 is a non-existent address.
  • Law & Order cast members Jerry Orbach and Jesse L. Martin make a crossover appearance when Detectives Robert Goren and Alexandra Eames discuss similar deaths in the area with them. This was the only appearance of either Lennie Briscoe or Ed Green on Criminal Intent.
  • The script from "Poison" was used for the Paris Enquêtes Criminelles first season episode "L'Ange de la mort".
