Veronica Guerin

On June 26, 1996, when Guerin was sitting in her red Opel Calibra at an intersection outside Dublin, one of two men sitting on a motorcycle beside her car fatally shot her five times. Guerin's murder caused outrage, and Taoiseach John Bruton called it "an attack on democracy". The following criminal investigation led to over 150 arrests and a hunt against Irish organised criminal gangs. There was also some discussion as to whether her newspaper shared any blame in her death for not preventing her more dangerous investigations.
n the wake of Guerin's death, the Irish parliament realised the potential of using tax enforcement laws as a means of deterring and punishing criminals. It then enacted the Proceeds of Crime Act 1996 and the Criminal Assets Bureau Act 1996, so that assets purchased with money obtained through crime could be seized by the government. This led to the formation of the Criminal Assets Bureau (CAB).

In November 1998, Dublin drug dealer Paul Ward was convicted of the murder and sentenced to life in prison as an accomplice because he had disposed of the pistol and the motorcycle. This conviction was later overturned on appeal, though Ward continues to serve a long prison sentence for his participation in a prison riot. Brian Meehan was convicted of murdering Guerin and sentenced to life imprisonment. John Gilligan was extradited from England on February 3, 2000. He was tried and acquitted for her murder but convicted of importing cannabis and sentenced to 28 years in prison; this was reduced to 20 years on appeal.

Two films have been based on her story: When the Sky Falls (2000, starring Joan Allen as "Sinead Hamilton"), and Veronica Guerin (2003, starring Cate Blanchett). The American progressive metal band, Savatage, included a song based on her story on their 1998 album, The Wake of Magellan. The Irish musician Christy Moore wrote a song, Veronica in her honour.
