A firearms dealer has been found guilty of supplying illegal handguns and home-made bullets linked to more than 100 crime scenes, including three murders.
Paul Edmunds, of Hardwicke, Gloucestershire, supplied ammunition used in an attempt to shoot down a police helicopter in the 2011 riots.
The 66-year-old was found guilty of conspiracy to supply firearms and ammunition by a jury at Birmingham Crown Court.
He will be sentenced on 20 December.
The court was told Edmunds, of Bristol Road, was arrested at his home in 2015, where he had three armouries he used to make bullets to fit antique weapons.
Detectives discovered that a Colt pistol – imported on November 14 2013 – was used five weeks later in a Boxing Day fatal shooting at the Avalon nightclub in London.
Four of Edmunds’ bullets were recovered from the victim’s body.
The jury were told Edmunds’ bullets were also recovered following the Birmingham murders of Derek Myers in 2015 and 18-year-old Kenichi Phillips in 2016.
Following his arrest, 100,000 live rounds were seized from the armoury inside Edmunds’ garage, while seven wheelie bin-loads of gun and bullet components were recovered from a bedroom and attic.
In all, 17 criminally-linked weapons recovered by police are known to have been imported by Edmunds, while around 1,000 bullets connected to him have been recovered from crime scenes in nine different police force areas.
In police interviews, Edmunds said he was “not responsible for the actions of somebody that buys some things”, adding his “duty of care” only extended to not selling to people who “didn’t look right”.
He told officers: “I’m not responsible for the actions of somebody that buys some things.
“Like me selling a knife and you take that knife and kill somebody and then the system blames me for selling you the knife.
“It’s your problem, got nothing to do with me.”
Jurors also convicted Edmunds of possessing a prohibited air pistol and perverting the course of justice by filing down a bullet-making tool to destroy potential evidence.
