Killing of Palmira Silva

Palmira Silva, aged 82, emigrated to London in the 1950s from Southern Italy with her husband Domenico, and was a widow. She was the proprietor of a café, and a great-grandmother with two children, six grandchildren and a great-grandchild.[1] Her daughter, Celestina, claimed that her mother wished to stay in Edmonton although "the area was changing".[2]

Silva's funeral was held on 24 September.[3] Her granddaughter Christina ran the 2015 London Marathon to raise money for Victim Support.[4]

Nicholas Salvador, aged 25 at the time of the killing, was staying with friends three doors from Silva's house.[5] He is an only child who came to the United Kingdom from Nigeria with his parents in his early teenage years.[2] After finishing a college course in Media, he had spells as manual labourer,[1][6] losing his job as a billboard paster three days before the killing due to concerns surrounding his behaviour.[5] He was active in cage fighting, and known as "Fat Nick" for his stature.[7]

Acquaintances said that he had issues with drug and alcohol abuse, and was a drug dealer.[6] His friends told the police that Salvador used cocaine and skunk cannabis, and would drink a bottle of whisky or brandy per day.[1] Contacts also revealed that he was obsessed with watching videos of beheadings and searching the Internet for Jihadist material.[8] He was also obsessed with the idea of shapeshifters.[5]

Two hours before the killing, Salvador ate at a café and left without paying. A staff member, who followed him out and successfully got him to pay, noted that "he seemed a bit depressed or upset about something".[6]

Shirtless, and armed with a knife and a broom handle, Salvador began to rampage, knocking down his neighbours' fences and beheading two cats. He broke into Silva's garden and she walked up to him, then he beheaded her. Police evacuated children in the area, and an officer gave the order "He's agitated and lethal... he needs taking out". After the police cornered Salvador, they struggled to arrest him, with one officer being assaulted by him. He had to be tasered six times. Salvador's rampage lasted for 45 minutes.[5][1]

Following Salvador's arrest, the Metropolitan Police reacted to speculation by stating that there were no links between his rampage and terrorism.[9] He was sent to Broadmoor Hospital, where psychiatrists found him to have paranoid schizophrenia.[1] Salvador believed Silva to be a reincarnation of Adolf Hitler or a shapeshifting demon,[5] and admitted to her killing.[1]

He was tried at the Old Bailey, where a 14-minute recording of his rampage was shown. On medical reports, he was found not guilty of murder by reason of insanity, but ordered to remain indefinitely in Broadmoor.[5] The judge, Recorder of London Nicholas Hilliard, concluded:

It is established beyond any doubt that you killed Mrs Silva in an attack of extraordinary brutality and ferocity. You thought you were encountering some demonic force which had taken on a human form. You could not have been more deluded. Nobody who saw it could forget the mild and trusting way Mrs Silva approached you over the wall while you were brandishing a knife. This gentle, intelligent 82-year-old lady should have been able to live her life in peace and with security, proud in the achievements of others, but that was not to be.[5]
