Jake Davison, who shot five people before turning the gun on himself in Plymouth last year, had previously been referred to a counter-terrorism program by his mother, an inquest has heard.
Davison, 22, was referred to the Prevent program – which aims to prevent people from becoming terrorists – by his mother Maxine in November 2016.
Details of the referral were not revealed at Tuesday’s pre-inquest hearing, but will be a key area of scrutiny when the inquest begins in January.
The apprentice crane operator shot and killed his mother, 51, after an argument in August 2021.
He kept on killing Sophie Martinthree, his father, Lee, 43, Stephen Washington, 59, and Kate Shepherd, 66, in the Keyham area of Plymouth.
the the attack lasted 12 minutesand took place just weeks after his shotgun and license were returned to him by local police after he assaulted two teenagers in a park last year.
The Independent Office for Police Conduct is investigating how Davison was approved for a weapon in 2018 and how it was returned to him.
As part of the investigation, two department personnel involved in the firearms license approval received serious misconduct notices and one officer received a misconduct notice.
Referring to the Prevent scheme, Ian Arrow, the Chief Coroner for Plymouth and South Devon, said: ‘To deal with the issues of November 2016 being the disclosure of the Prevent scheme made by Ms Davison.
Mr Arrow added that those involved in the scheme could be asked to be “interested persons”, and that they could be legally represented and be able to ask questions of witnesses.
He told Plymouth Coroner’s Court that next year’s inquest would also look into how Davison’s shotgun application was handled by police, his referral to the scout program and how the allegations of assault against him had been dealt with.
He will also consider the seizure and subsequent return of his shotgun and license weeks before the murders.
The shooter’s contact with mental health services in May 2021 would also be considered.
It is believed that Davison had a obsession with incel (involuntary celibacy), as well as an interest in firearms and the United States, and reports suggested that his mother had struggled to get help for him and his mental health.
Jason Beer QC, representing Devon and Cornwall Police, said police were still investigating the events of last summer, including Davison’s use of Reddit chat rooms – which the force are in contact with .
“A review of Jake Davison’s computer tower and cellphone showed that he was an active member of the Reddit forums,” Beer said.
“Some of them were incel related. Some forums were pro-incel and some were anti-incel.”
The inquest heard that a police peer review firearm licensing procedures was undertaken, with a number of recommendations made, including for a “more robust system”.
Psychological reports on insanity killers, incel-motivated killers and “similarities or differences with Jake Davison and the prevalence or otherwise of steroid abuse in the commission of violent crimes”, were commissioned by police, Mr. Beer said.
Another pre-inquiry review will take place on December 19.
