Calling card (crime)

A calling card is a particular object sometimes left behind by a criminal at a scene of a crime, often as a way of taunting police or obliquely claiming responsibility. The name is derived from the cards that people used to show they had been to visit someone's house when the resident was absent.

Historical examples

* The Washington D.C. Beltway sniper attacks in 2002 were linked by a series of Tarot cards left by the snipers, which contained messages for the policemen investigating the crimes.
* Jack the Ripper is believed to have left two calling cards by Goulston Street, London on September 30, 1888, the night he murdered Elizabeth Stride and Catherine Eddowes: a scrap of Eddowes' apron and some graffiti reading "Juwes are the men That Will not be Blamed for nothing". Some authors believe the graffiti may have already been there prior to the apron piece being dropped and that the two should not be linked.
* The 1968 Zodiac Killer in San Francisco would mail cryptograms to the San Francisco Chronicle made up of letters and zodiac signs, signed with a sun cross.

Examples in fiction

* In the 1990 film "Home Alone", the "Wet Bandits" rob the houses of people on vacation, and then leave the water running. They return as the "Sticky Bandits" in "Home Alone 2".
* In the 2000 book "Angels and Demons" by Dan Brown, a Hassassin uses brands representing the four classical elements as calling cards in a series of ritualistic murders related to each element (e.g. fire for one victim who had been burned to death.)
* In DC Comics, Batman's enemies often leave calling cards. In particular, his arch-enemy, The Joker, uses two types of calling cards, one is a simple joker card from a deck of playing cards, which was used in the end of the film Batman Begins. The other is by far more sinister - Joker Venom, which causes death while laughing madly and applies a permanent, ear-to-ear, grin.
*In the 2004 movie "Saw" the killer, Jigsaw, cuts a jigsaw piece out of the flesh of the victim, symbolizing the piece that the person was missing.
