A 50-year-old Kent man who was found guilty of murdering his brother has been found dead in his cell.
Bill Treeby, of Paddock Wood, died at Elmley Prison on Sheppey on Sunday.
He was due to be sentenced on Wednesday alongside his sons Billy Treeby, 29, and George Treeby, 23, both from Paddock Wood, for the murder.
A spokesman for the Prison Service said Bill Treeby was found hanged in his cell. Attempts were made to resuscitate him, but he was pronounced dead.
He added: "As with all deaths in custody, there will be an investigation by the Prisons and Probation Ombudsman."
Murder victim Jack Treeby, 43, died after being knocked down by a Range Rover in Tovil, near Maidstone, on 27 December last year.
During a trial at Maidstone Crown Court, jurors heard how tensions involving a property dispute built up between the two sides of the large family.
Kent Police were called to Quarry Road just before 1900 GMT to men lying injured in the street and a car ablaze.
Jack Treeby had died from his injuries after being run over. His son, Jack Treeby junior had suffered injuries in a car collision. Gary Treeby, Jack senior's brother, had received a bullet wound.
On Friday, Bill, Billy and George Treeby were convicted of murder, while Bill Treeby's wife Charity Treeby, 51, was cleared of the same charge.
The three men were also found guilty of attempting to murder Gary, and Charity Treeby was convicted of causing grievous bodily harm with intent to Gary.
All four, of Queen Street, were cleared of the attempted murder of Jack Treeby junior and attempting to cause him grievous bodily harm.
Charity Treeby is also due to be sentenced at Maidstone Crown Court on Wednesday.
