Two teens who murdered a factory supervisor by slashing him more than 100 times with a samurai sword have been sentenced to life.
Kiyran Earnshaw, 18, and Luke Gaukroger, 16, have been sentenced at Leeds Crown Court to life with minimum terms of 22 years and 16 years, eight months respectively, for murdering Robert Wilson.
CCTV footage, played in court on Wednesday, showed how 53-year-old Robert was investigating youths hanging around outside the Thornton & Ross pharmaceutical plant in Huddersfield when he was attacked by Earnshaw and Gaukroger, who passed a 20 inch sword between them.
A recording, played in court, captured the night shift supervisor's pleas to the youths to stop their attack.
Leeds Crown Court heard that Mr Wilson was married with two grown-up children and enjoyed gardening, golf and walking in the Yorkshire Dales.
His wife Elaine told the court his death was "completely incomprehensible", adding: "How on earth have we come to this and why?"
She said she was sickened to receive a letter from one of the defendants saying it was the "worse night of my life and 'I'm sorry"'. She told the judge she had been shocked to "feel so much hate".
She said to the defendants: "I want you to know you have taken the life of a much respected, admired and good man."
Peter Makepeace QC, prosecuting, told Leeds Crown Court that Earnshaw started the attack after producing the blue sword from inside his tracksuit bottoms.
After he started raining blows on Mr Wilson, the younger teenager was heard repeatedly shouting: "Pass me the shank, pass me the shank."
After multiple blows and kicks to Mr Wilson, Earnshaw passed the sword to the other defendant.
Mr Makepeace said the pair paused at one point to catch their breath and to rifle through Mr Wilson's pockets, taking his coat.
Earnshaw was Tasered twice before he was arrested and officers used an incapacitant spray on the boy.
The court heard that Mr Wilson had left the plant to talk to the youths in the car park with colleagues Paul Thewliss and John Badejo.
Mr Badejo was seriously injured as he tried to help his friend and both men were forced to flee for their lives, Mr Makepeace said.
He said: "There is no suggestion they were anything other than polite and decent in their dealings with the youths once they met up in the car park."
