A man who knifed his "controlling" stepfather to death after a long-running family feud boiled over has been found hanging in his cell.
Nathan Vaughan-Jones, 34, was found at Lewes prison in East Sussex at about 8.30pm on Friday and pronounced dead about half-an-hour later, said the Prison Service.
He was jailed for 11 years in March after he pleaded guilty to the manslaughter of 63-year-old Nigel Ross on the grounds of diminished responsibility.
He stabbed Mr Ross 41 times in the garden of his sister's home in Mill Lane, South Chailey, near Lewes, East Sussex, on March 29 last year.
Days earlier, Vaughan-Jones had returned to Britain from Bermuda, where he lived with his wife, to hear of Mr Ross's "dominating" attitude towards other family members, Maidstone Crown Court heard.
A Prison Service spokeswoman said: "HMP Lewes prisoner Nathan Vaughan-Jones was found hanging in a cell at approximately 8.30pm on Friday July 27.
"He was pronounced dead at approximately 9pm.
"As with all deaths in custody, the independent Prisons and Probation Ombudsman will conduct an investigation."
It is understood Vaughan-Jones was not subject to suicide prevention measures.
