A 74-year-old who walks with a stick killed her younger partner with a single stab to the heart, a jury has heard.
Angela Ayre, a former Avon lady, is accused of knifing her live-in boyfriend Mark Evans, 54, after he urinated in the conservatory at their home in Dunstable, Beds.
The pair had been drinking heavily, with the victim found to be three times over the legal drive limit and Ayre two times over, Luton Crown Court heard.
Police and ambulance crews were called to the semi detached house at 11.12pm on the night of March 8 last year.
Mr Evans was pronounced dead at the scene.
A post-mortem examination by pathologist Dr Charlotte Randall found that the stab wound was 2cm wide and entered the left side of his chest below the left nipple.
Prosecutor Charles Ward-Jackson told the court that the knife had entered Mr Evans’ body ‘up to the hilt’.
‘It was orientated almost vertically. If one were looking at a clock face it would be between 1 o’clock and 7 o’clock,’ he said.
‘The sharp side was uppermost with the knife being held upside down. It is possible the knife had been gripped in an underarm motion. The depth of the wound was 10 centimetres.
‘The knife was 8 and a half centimetres in length. It went right in – up to the hilt.
‘The defendant says what happened was an accident, but the knife went through skin and muscle, under the sixth rib and into the left ventricle of the heart.’
He told the court that the couple had been ‘drinking to excess’ before a row broke out when Mr Evans urinated in the conservatory.
‘A blood sample taken from Mr Evans gave a reading of 252 mg of alcohol per 100 ml of blood with the drive limit being 80. Angela Ayre gave a reading of about twice,’ he said.
Ayre, of Redfield Close, Dunstable, denies murder.
David West, a life-long friend of Mark Evans, told the court on January 4 that a year and a half to two years ago he received a phone call from Ayre in which she said she thought she had killed her partner.
Mr West stated that he and his wife Sarah West went round to the house to find that Ayre had knocked Mr Evans unconscious and coming round.
‘I asked if he was ok. His response was that Angela was washing up. He went behind and her grabbed her breasts and she elbowed him in the forehead,’ he said.
‘We stayed there for half an hour to 40 minutes to make sure he was ok and then we just left.’
Mrs West, who works at the Co-op in Westfield Road, Dunstable told the jury she would often sell the couple vodka.
The trial continues.
