Andrea Arrigoni

Andrea Arrigoni (13 January 1969 – 21 February 2005) was an Italian serial killer and former private investigator who killed at least two prostitutes and two police officers in two separate incidents from 2004 to 2005. He was killed in a firefight with police, and was posthumously linked to his first known murder.

Early life and career Andrea Arrigoni was born in 1969 in Bergamo, the younger of two sons born to marching band director Alberto and volunteer nurse Mariuccia Arrigoni. His family was well-regarded in his hometown due to the fact that both of his parents engaged in volunteer work, and raised their children seemingly without any issues. Whilst growing up, Arrigoni was described as a fun-loving prankster who got along with everyone. Three days later, her body was found in a canal in Osio Sopra - she had been decapitated and her hands amputated, but this seemed to have been done post-mortem, as the head had a single gunshot wound. Coroners determined that the killer had used a Beretta pistol with 6.35 mm rounds. She was identified via her piercings and a tattoo on her body, but her killer remained elusive for the time being. The pair eventually got into a violent altercation that was notified to the police.

In response two police officers were dispatched to arrest Arrigoni, but by the time they arrived, he had already shot Shafranek in the neck with his pistol. The officers, though wounded, were able to return fire, killing Arrigoni. The gravely injured Shafranek was taken to a hospital, but succumbed to her injuries.

This revelation led the local police department to officially label him a serial killer, as well as prompting them to investigate whether he could be responsible for other unsolved murders committed around Italy. At some point it was suggested that Arrigoni might have been the perpetrator of the Piazzale Dateo murders, an unsolved triple murder committed in Milan on December 31, 1999. The victims in that case - 29-year-old Brazilian transvestite Paulo Barboza dos Santos, his 51-year-old "friend" Pierfranco Talgati and 27-year-old Sri Lankan passer-by Clement Wattoru Tantirige - were all shot with a weapon using 9×21mm rounds used by law enforcement. In addition, it was determined that the killer had committed various thefts and robberies using a stolen black Porsche that was later found burned down.

Aftermath Arrigoni's motives for the murders remain unclear. Hypotheses have ranged from him being a pimp to being a government spy seeking information in violent ways. She is now a law student and has considered becoming a policewoman like her father, but has said that the profession is not necessarily her priority.
