Killing of Palmira Silva

On 4 September 2014, 82-year-old Palmira Silva was beheaded in her back garden in Edmonton, London, by 25-year-old Nicholas Salvador, who was on a rampage. Friends of Salvador had recently noticed odd behaviour by him, including drug and alcohol abuse and an obsession with videos of beheadings.

Psychiatrists found evidence that Salvador had paranoid schizophrenia. On 23 June 2015, he was found not guilty of murder on basis of insanity, and was detained indefinitely in a psychiatric hospital.
