Woman jailed for killing partner at Bedford home
A 40-year-old woman has been jailed after pleading guilty to the manslaughter of her partner at their home in Bedford.
Marie Gavin attacked Polish born Piotr Plonka, 34, with a hammer before stabbing him at their home in April.
She was given an indeterminate sentence and told she would serve a minimum of seven-and-a-half years before being considered for release.
Judge Michael Baker QC said Gavin posed a threat to the public.
The couple had been in a six year relationship and were both heavy drinkers.
Although the relationship was described at Luton Crown Court as enduring with genuine affection between them, it had been marred by violence on both sides.
Gavin had in the past accused her partner of rape which proved to be false.
On 22 April, hours before the killing, Gavin had fallen over in Tavistock Street in Bedford.
She went to hospital where she was told she was not hurt but was then violent and abusive to staff.
Russell Gumpert, prosecuting, said Mr Plonka apologised to staff and they returned to their Putnoe home in a taxi after stopping to buy a large bottle of cider.
The prosecutor said: "They were dropped off at home at 01:23 BST. Shortly after that Marie Gavin killed Pietr Plonka."
The next day friends of the defendant found the body on the living room floor covered in a duvet.
Knife wounds had punctured his lungs which caused him to bleed to death.
Gavin said she had no memory of the events that night, but now accepted she did commit the killing.
Earlier this year her guilty plea to manslaughter on the grounds of diminished responsibility had been accepted by the prosecution.
Judge Baker told Gavin: "At some point, probably soon after your arrival home, you killed him. No one will know why."
The judge said she posed a significant risk of causing serious harm to members of the public by further offences.
