An inmate who killed another prisoner with a single punch in an unprovoked attack has been jailed for four years.
Keiron Simpson, 26, was serving a prison sentence at HMP Doncaster when he attacked and killed Robert Bryan on February 27.
During free time for the prisoners in the evening, Simpson had walked up behind Bryan and punched him in the face, knocking him unconscious.
The fall resulted in Bryan fracturing his skull and caused him a brain injury.
He died in hospital the same evening.
Simpson was sentenced to four years in jail - half of which he will serve on licence - at Sheffield Crown Court today having pleaded guilty to manslaughter at an earlier hearing.
Simpson, formerly of Smithywood Lane, Dodworth, Barnsley, was serving time in jail for burglary, shoplifting and drugs offences when he attacked his victim, who had been recalled to prison to serve out the remainder of a manslaughter sentence.
A victim impact statement from Bryan’s former partner was read out in court and said his seven-year-old daughter had been deeply affected by her father’s killing.
Sean Fritchley, defending Simpson, said the attack had been caused by a ‘prison-yard slight’ and his client had not meant to kill Bryan, who was from Rotherham.
Mr Fritchley said: “He knows custody is inevitable. It was a single blow and he has to live with that now for the rest of his life.
“He knows it had a tragic impact on the victim’s family and daughter. If he could turn back the clock, he would.”
Sentencing, Judge Julian Goose QC, Honorary Recorder of Sheffield, told Simpson it had been an ‘entirely unprovoked attack’.
He said: “While you believed that he would not die, it is clear that by our actions, you have ended his life.”
Detective Sergeant Andrew Knowles, investigating officer for South Yorkshire Police, said: “This case clearly shows how dangerous and devastating just one punch can be.
“Simpson attacked Bryan for no apparent reason. He may not have intended to kill him but anyone who makes the decision to strike another with force must consider the potential shattering consequences a single punch can have.
“South Yorkshire Police will thoroughly investigate the circumstances of unlawful deaths, whether it occurs inside a house or inside a prison and those who are to blame will be held to account for their actions.”
