Hayley Keating, 31, is accused of killing her partner with a knife during a drug and alcohol-fuelled rage when he attempted to leave her. The victim had told his friends that Keating was "a nutter but the sex was really good".
A jury at Bristol Crown Court has heard how a mother-of-two killed her boyfriend by throwing a large kitchen knife that penetrated four inches into his chest.
31-year-old Hayley Keating is accused of murdering her partner and father-of-two, Matthew Wormleighton. Mr Wormleighton had previously told friends that Keating was "a nutter but the sex was really good".
Prosecutors claimed that during the early hours of May 14, 2021, Keating took a knife from the kitchen and threw it at Mr Wormleighton during a drug and alcohol-fuelled rage.
The couple had been together for three years. The jury at Bristol Crown Court were told that the knife dug 10 centimetres into Mr Wormleighton's chest.
The court heard how Keating had phoned emergency services and told the operator that she had stabbed her partner, however, prosecutor Jo Martin QC said this account "may not be right".
Ms Martin told the jury how Keating now claims "she threw the knife in his direction" and that "she does not know how he became injured, and she cannot remember what happened".
Ms Martin requested that the jury put considerable thought into how the knife ended up so deep into Mr Wormleighton's chest and whether Keating did throw the knife or if she purposefully stabbed him.
She added that the defendant was "angry and upset" because Mr Wormleighton was "trying to leave her", she also stated that her anger was exacerbated by drugs and alcohol.
The defence's case stated that the victim had previously been violent toward Keating in the past and that he had frightened her on the night of the killing.
The jurors listened to the defence saying that Mr Wormleighton was controlling and coercive towards the defendant.
Mr Wormleighton had two previous long-lasting relationships, both of the women confirmed that he was never violent or controlling towards them and described him as "caring, generous, and a loveable rogue".
The court heard how both of them were frequent users of alcohol and cocaine and suffered from depression. Keating denies murder and the trial continues.
