Sheffield Crown Court has heard during a trial how the 16-year-old Sheffield boy, who cannot be named for legal reasons, and 50-year-old Richard Sampson, of Prince of Wales Road near Woodthorpe, Sheffield, den 42 year olds attacked Anthony Sumner in Windy House Lane, Manor, Sheffield.
Prosecutor Michelle Colborne QC said the youth was armed with a knife and Sampson with a machete when Mr Sumner was attacked on July 29, 2021 after Mr Sampson believed Mr Sumner broke his windows.
According to Ms Colborne, the defendants were allegedly captured on CCTV behind Anthony Sumner and a friend, and after the friend went to his home, Mr Sumner was attacked.
Ms Colborne said: “Anthony Sumner was defenseless when he was pursued and cornered by them in a garden.”
She added that Sampson attacked him with a machete and aimed blows at his head and torso, hitting and injuring his left wrist, and the youth – armed with a knife – stabbed Mr Sumner’s chest area.
Anthony Sumner stumbled into the street and collapsed in front of neighbors and friends and died just after midnight on July 30, 2021, according to Ms Colborne.
Ms Colborne said Anthony Sumner injured his head with a machete and his chest with a knife and the stab wounds and resulting blood loss and breathing problems resulted in his death.
Ms Colborne said the youth called a relative and allegedly confessed that he had stabbed someone and that he believed that person had died.
Both Sampson and the Sheffield youth pleaded not guilty to murder and possession of an obnoxious weapon in a public place without legal authority or a reasonable excuse.
However, the jury found the youth guilty on June 30 of murder and possession of an assault weapon. The jury also formally found Sampson guilty of possession of an offensive weapon, but they have yet to reach a verdict on the murder charge he still faces.
Machete murder suspect claims he had no intention of killing Sheffield man Ant…
Sampson claimed to have found the machete behind a trash can and he accepted the injury but claimed he had no intention of grievously injuring or killing Mr Sumner, despite hitting him with the machete.
He also claimed he did not stab the deceased and that he was not aware that the youth had a knife or that that person would use one to stab Mr Sumner.
Sampson said Mr Sumner started throwing flower pots and Sampson said he was trying to protect himself and he just hit him with the flat side of the machete.
Ms Colborne said despite the best efforts of paramedics, Mr Sumner died on the road just after midnight on July 30, 2021.
The trial jury continues its deliberations on Sampson.
