Er Canaro

Pietro De Negri, better known as Er Canaro (Roman dialect: "the dog keeper"; born 28 September 1956), is an Italian criminal, a dog coiffeur (hence the nickname) and a cocaine addict.

De Negri was born at Calasetta, in Sardinia. Later he lived in the Rome's neighbourhood of Magliana. At the age of 27, he killed former boxer, quarter tough guy, and fellow cocaine addict Giancarlo Ricci. The so-called Canaro's killing (Italian Delitto del Canaro) is notable for being one of the most gruesome crimes carried out in Italy since the end of World War II, particularly because the victim watched powerless during the excessive mutilation.

On February 18, 1988, Ricci entered into Pietro De Negri's shop as usual, beating and slapping him as he had on previous occasions. De Negri had been a victim of Ricci's physical abuse before, but had conceived a plan to kill him. He told Ricci that a cocaine pusher was coming into the shop, and that if Ricci would hide himself into a dog cage, they could steal the pusher's cocaine and money. As soon as Ricci entered into the cage, De Negri locked him inside. He tortured Ricci for seven hours, left him tied with a chain, went to his daughter's school to take her home, and later returned to his shop.

Ricci was tortured to death, with some of his fingers having been removed and put inside bodily orifices. Pieces of his face were cut, his tongue was removed, and his penis was put into his mouth, which caused him to die of asphyxiation, according to the post-mortem. De Negri also pierced one of Ricci's eyes with the cut fingers, smashed his teeth and head with a pipe wrench, and "washed" his brain with dog shampoo.

The morning after, Ricci's body was found in a landfill, still smoking, as De Negri had thrown fuel onto the body and tried to burn it. A man that had driven Ricci to the shop the day of the murder admitted what he had done, and De Negri confessed his murder. After conviction, he served 16 years out of his 24-year prison term.
