**The details:** The teenager, who cannot be named for legal reasons, appeared at Ipswich Crown Court on Friday, 17 April, where he was given a 36-month rehabilitation order with intensive supervision and surveillance.

He was found guilty in February of the manslaughter of Mr Roche, a 42-year-old father-of-three, who died after an altercation began in Ulster Avenue, Whitehouse, on 25 July last year. Mr Roche was taken to hospital but died on 11 August.

**What the judge said:** Judge Samantha Leigh told the hearing that the teenager had the mental age of a nine-year-old and that his "childlike thinking" had led to him lashing out in an instinctive reaction.

**For context:** Fellow accused Thomas Watchman, 39, of Wicklow Road, was acquitted of manslaughter in February but found guilty of assault by beating. He received an eight-week jail term, which he had already served during his time in custody.

**What they're saying:** Detective Inspector Dan Connick, who led the investigation for Suffolk Police, paid tribute to Mr Roche's family following the sentencing. 

"They have displayed a great dignity throughout the investigation and trial while dealing with a terrible personal tragedy," he said.

Detective Superintendent Phill Gray, head of the Joint Norfolk and Suffolk Major Investigation Team, issued a warning last year about the dangers of avoidable confrontations escalating into tragedy.

"There is no defence for any violence in this way. My message is quite simple: if tensions rise, de-escalate the situation or simply walk away," he said. "You might think punching someone once is not a big deal; cases like this prove otherwise."

**The bottom line:** A rehabilitation order – rather than custody – reflects the court's assessment of a defendant whose developmental age, the judge found, was far below his years, in a case that police say underlines how quickly a single punch can end a life.
