Exclusive: Jake Davison seen pacing around convenience store for more than five minutes on day before attack
Police increasingly believe that anti-women propaganda may have fuelled anger in the Plymouth gunman before his attack, with his links to the “incel” movement a main strand of their investigation.
Jake Davison, 22, shot dead his mother and four other people on 12 August. It emerged that he had engaged with extremist ideology including the “involuntary celibate” movement, though this is not considered to be enough for security officials to declare the mass shooting as a terrorist attack. Counter-terrorism officers continue to aid the investigation as detectives trawl through the attacker’s electronic devices.
