Jurors heard after the attack the pair returned to Winn Gardens estate where they lived - "boasting" about what they had done

Leon Gray and Lewis Barlow were aged just 14 when in April 2007 they beat a partially-sighted man to death at a Sheffield tram stop.

During the "gratuitous, unprovoked and sustained violence" the teens punched, kicked and stamped on 45-year-old Colin Greenwood.

Following the savage beating at the Middlewood terminus on April 13, father-of-five Colin died the following day.

Gray and Barlow both denied murder however during their trial jurors heard after the attack they returned to Winn Gardens estate where they lived - "boasting" about what they had done.

The pair were convicted for murder and handed at least 12-and-a-half years’ jail in October 2007.

But this was quashed by the Court of Appeal the following year and they were resentenced with four years’ jail each, having admitted manslaughter.

Judge Alan Goldsack QC heard how alcoholic Colin was well-known locally for yelling abuse back at tormentors and the two boys were baiting the victim on the day of the attack.

They taunted Colin - with Barlow throwing a mock punch and Gray threatening him with a penknife. However when he retaliated, kicking out at the boys, Barlow punched him to the ground.

Barlow then stomped on the victim's chest and head before Gray kicked him at "full pelt" to the side of his head, connecting with his temple and causing his head to hit the kerb.

Colin later continued his journey, however as he got off a bus he collapsed and was taken to hospital where he died the next day from a head injury.

Jurors heard Colin was on his way home from seeing his five children - aged between four and 11 - at his former partner's home when the attack unfolded.

He was described in court as "vulnerable", and not only “visually disabled” but also “highly intoxicated” as a long-established alcoholic.

At their first sentence hearing, after being found guilty of murder, Judge Alan Goldsack QC said: "You decided you would have what one of you described to another as a bit of fun.

“You had, in reality, kicked this man to death. It was gratuitous, unprovoked and sustained violence and in so far as there is an explanation, it appears to lie in your family backgrounds and the culture in which you've grown up.”
