A police officer has said the father and son who were jailed for the vigilante murder of a thief had an "obsession with weapons".
David King, 56, and his 20-year-old son Edward have been handed life sentences for the murder of Neil Charles in June 2021 in Bury St Edmunds.
Mr Charles was attacked by the pair after trying car door handles at their home in Radnor Close.
Tesco worker Edward King left his house with a two-foot-long sword in pursuit of Mr Charles, while his father armed himself with a dagger.
Mr Charles, 47, was fatally stabbed by the dagger and sliced across the knee by the sword, in the early hours of June 20, Ipswich Crown Court heard.
Prosecutor Richard Kelly described it as "vigilante behaviour" by the father and son duo.
When the King's home was searched following their arrests, officers found numerous weapons – including lock knives, knuckle dusters and a samurai sword.
Speaking after Monday's sentencing, Detective Chief Inspector Karl Nightingale, of Suffolk police, said: "Today's sentence brings this case to a close. It will bring some element of closure to the family after David and Edward King were convicted last May.
"This has been long-awaited. The family have said the sentencing is positive but there are no winners here.
"The prosecution was clear from the outset that Neil was actively committing crime on the night he was killed, trying door handles of cars and addresses.
"Neil did exactly that at the property of the King family.
"However, the trial proved that the actions of the Kings were not spontaneous. Their obsession with weapons, pride over their possessions and threats to harm people who offended them dated back years prior to the killing of Mr Charles.
"David and Edward King have shown arrogance and contempt throughout.
"At no point have they shown any hint of genuine remorse or humility for their actions, convincing themselves they did nothing wrong at all.
"The vigilante conduct of David and Edward King has destroyed many lives, changed families and impacted their own community."
