Jones wept as he was led from the dock
A man has been jailed for life for the murder of his ex-wife as she prepared for a divorce party.
Brian Jones, 63, used a kitchen knife to stab mother-of-two Katrina Jones 12 times at her home in Marske, Teesside, last November.
Jones, also of Marske, admitted stabbing Mrs Jones but denied murder, claiming the party had provoked him.
He was convicted of the 34-year-old's murder at Teesside Crown Court and will serve a minimum of 10 years.
On the day of the murder, posters had been put up saying "Katrina's Divorce Party. Free at last".
The bodybuilder snapped after seeing one photograph of his face with "Pin the tail on the X" written next to it.
The jury took eight hours to convict Jones of murder, by a unanimous verdict.
Jones was arrested on 27 November after he called 999, telling an operator: "I have stabbed my wife, please come quickly. Will you please come and save her?"
Divorce party banner
Police and paramedics found Mrs Jones's body on the living room floor of the house in Church Close, Marske, Teesside.
She had a divorce party banner draped across herself.
The court heard during a two-week trial that a month before the killing, the couple's 10-year marriage was legally dissolved.
Jones said he had no memory of stabbing his ex-wife Katrina
Seven months earlier Mrs Jones filed for divorce, citing her husband's "unreasonable behaviour" as the reason for the petition.
It later emerged that Mrs Jones had been having an affair with a friend from her past for more than a year.
Jean Evans, Katrina's mother said: "My life has changed forever and it will never be the same again."
Det Sgt Colin Helyer said: "This is one of the most extreme cases of domestic violence that I have ever dealt with and the victim endured months and months of abuse which has ultimately led to her death.
"Throughout the court case, Katrina's family have had to listen to a lot of painful and upsetting evidence given by various witnesses. They have remained dignified throughout this time.
"This is a just result for a horrific crime. I only hope that it brings some closure for the family and they can now move on with their lives.
Jailing Jones, the Recorder of Middlesbrough Judge Peter Fox said: "Your intention, I am clear, was to kill her."
