Pseudonyms: Criminals

It seems that many major criminals either take on pseudonyms (aliases) or have them assigned to them.

The Unabomber (Ted Kaczynski) was assigned his pseudonym from the FBI acronym for UNiversities and Airline Bomber.

New York Police discovered in 1977 a handwritten letter near the bodies of two victims that was addressed to a NYPD Captain. In the letter, the killer referred to himself as "Son of Sam" for the first time. The press had previously dubbed the killer "the .44 Caliber Killer" because it was the weapon of choice for serial killer David Berkowitz.

Here are some of the better known criminal pseudonyms and their owners.
