Dempsey Nibbs found guilty of beheading partner Judith Nibbs
A man has been found guilty of beheading his long-term partner at their east London flat before flushing the remains down the toilet.
Crane driver Dempsey Nibbs killed Judith Nibbs, his partner of 30 years, after he became angry when she admitted to having affairs.
Nibbs, 69, of the Charles Estate in Hoxton, had denied murder.
Judith Nibbs, 60, had confided in her sister and a colleague that her partner had threatened to kill her.
Nibbs attacked the mother of his two children with an iron bar at their flat in April 2014, the Old Bailey heard.
He cut off her head, before smashing it and disposing of pieces in the toilet.
Nibbs called 999 to say police would find two bodies at the property.
A police officer broke down the door when he saw a headless body through the letterbox.
He then grappled a shotgun and knife from Nibbs, who was attempting to stab himself.
'I might be dead'
Mrs Nibbs, originally from Kirkham, Lancashire, was described as "bubbly and happy" but had confided in her sister and a colleague that her partner had threatened to kill her.
The couple were not married, but had been together for 30 years, had two children and she had taken his surname.
Mrs Nibbs was referred to as the accused's "wife" during the trial.
Their relationship soured in the spring of 2014 as Nibbs suspected her of having affairs, the court heard.
During a row Mrs Nibbs admitted seeing other men, taunting Nibbs by saying: "I have had sex eight times."
The next day she predicted her own killing as she left work, with the words: "If I'm not in Friday, I might be dead."
Nibbs told jurors he had not meant to kill his partner when he went to confront her over her infidelity.
He said he had only meant to "slap her around a bit" and it was only after she was dead that he cut her head off in anger because she "betrayed" him.
The jury rejected his claim of self-defence and found him guilty of murder.
Sentencing was adjourned to a date to be fixed.
