Edgington has a younger brother and younger sister and attended Sackville School. Edgington told police that she was abused by her father when younger. She shoplifted during her adolescence and used violence against her brother and mother since childhood. She had stays in care homes at times. She worked as a hairdresser, shop assistant and saleswoman. According to the Daily Mail she has been a prostitute, pole dancer and drug dealer. At age 17, Nicola miscarried twins after being punched in the stomach by a violent boyfriend and at 19 she was pregnant again, by a drug-dealer boyfriend, and gave birth to a son three months prematurely. It was Marion (Nicola's mother) who helped Nicola care for the baby,until Marion gave the boy to social services foster care. Edgington married a Jamaican man who is the father of her younger son. The sons were taken into care and then to Jamaica by her ex-husband.
Killing of her mother
On 4 November 2005, Edgington stabbed her 60 year old mother, Marion, nine times in Forest Row, East Sussex for which she was convicted of manslaughter due to diminished responsibility (based on diagnoses of schizophrenia and emotionally unstable personality traits) at Lewes Crown Court on 23 October 2006. She was detained indefinitely under the Mental Health Act 1983 and, following treatment and psychiatric evaluation, was released conditionally in September 2009, moving into a Greenwich flat.
Killing and attempted killing of strangers
In September 2011, Edgington sent a message via Facebook to her brother saying she wasn't getting the help she needed, missed her mother, and had had a miscarriage. She left her phone number and asked him not to tell their father, Harry, that she had made contact. Her brother replied that she killed their mother and he found the body, that the miscarriage was good news, and that she should kill herself by cutting her wrists.
On 6, 7 and 9 October, Edgington contacted police several times by phone and once in person reporting that individuals were making death threats against her (naming one individual), and later that two cocaine users were refusing to leave her flat and may have stolen from her. Despite initially being graded as serious and requiring police attendance, no police were dispatched to investigate.
On the morning of 10 October 2011, Edgington pleaded numerous times with police and local mental health services to physically detain her under their legal powers as she felt she was having another psychotic breakdown, saying she had killed someone before and that the more scared she became the more dangerous she could be. Although taken to Queen Elizabeth hospital, she was left there by police prior to being securely admitted, and the psychiatric staff decided they were only going to admit her on a voluntary basis despite her risk profile and secure care plan being in her psychiatric file.
Later in the morning of 10 October 2011, while waiting for staff to change shift and admit her, Edgington left the hospital through a door that should have been locked, took two buses, and stabbed two strangers in the street in separate attacks in Bexleyheath. She bought a knife from Asda with which she tried to kill 22 year old Kerry Clark, who survived and took the knife off her. Edgington subsequently stole a knife from a butcher's shop and stabbed 58 year old Sally Hodkin, who died of her injuries within minutes. Edgington was arrested later the same morning.
According to psychiatrists, Edgington was suffering from paranoid delusions and hallucinations, with a religious subtext. She believed a 100-eyed monster was guarding the throne of God against enemies, and saw shops looking like a nuclear holocaust had taken place; she believed Jesus had come back to save everyone's souls except hers which she couldn't understand as she loved God. She also felt she was in a computer simulation and had various bizarre beliefs relating to famous figures and films.
On 7 February 2013 at the Old Bailey, Edgington was convicted by jury of the attempted murder of Clark and of the murder of Hodkin. Judge Brian Barker jailed her for life on 4 March 2013, with a minimum tariff of 37 years. Barker wrote that despite Edgington's firm long-standing diagnosis of schizophrenia and probable psychosis around the time of the attacks, he believed the over-riding factor was borderline personality disorder (in the UK usually referred to in ICD terms as Emotionally Unstable Personality Disorder, Borderline Type) with rational ability. He referred to a recent medical report indicating no need for hospital treatment for Edgington. Despite Edgington having sought multiple times to have herself detained by the police or medical services prior to her actions, Barker stated that the killing was premeditated in a way that showed a "consistent and calculated course of criminal conduct". Barker included the random and unprovoked nature of the attacks as aggravating factors indicating more guilt, while disregarding the mitigating factor of mental disability since the psychiatric authorities disagreed about it.
