The horrifying audio clip of Shane Clarke’s phone call to the emergency services was released after he was sentenced to life behind bars.
Clarke, 52, brutally killed his girlfriend, Joanne Bishop, 39, at their home in Milton Keynes, Bucks on 29 May this year.
He stabbed Ms Bishop 29 times with a screwdriver before leaving her and going to the pub.
Clarke appeared “calm and relaxed” during the phone call, Oxford Crown Court heard, and was even heard chuckling away as he told the operator he had killed his girlfriend.
In the phone call, Clarke told the call handler he had “just stabbed the missus” and shocked by the calmness in his tone, she replied “you’ve what, sorry?”
Clarke laughed as he told the call handler “I think she’s gone”, “I think she’s dead, mate”.
The operator asked Clarke to go back in the house to check on Ms Bishop but he refused, saying “no, I don’t want to go back there”.
Police arrived at the scene and arrested Clarke on suspicion of murder, but then re-arrested him on suspicion of attempted murder when paramedics found his victim alive.
He was heard telling officers: “S**t way to start a Tuesday morning, costing the Government a million quid.”
After paramedics managed to revive Ms Bishop, Clarke said: “Sweet. That’s brill. F**k those ambulances are great aren’t they.”
However, she died of brain damage at hospital four days later.
Sandra Bishop, the victim’s mother, said: “I would lie awake at night unable to sleep thinking about what happened in that room, the pain she went through, what she was thinking about during the attack.”
Clarke was sentenced to prison for life, with no chance of parole for 20 years.
Judge Pringle at the Oxford Crown Court agreed to sentence Clarke for murder.
He said: “I will never understand what Shane did and not forget what he did that day.
“The sheer nature of this attack was utterly brutal.
“The use of a screwdriver to attack the victim was appalling. The number of times that screwdriver was inserted into his victim – no less than 29 times – almost beggars belief.
“It is said that the defendant reacted in this way because of something Ms Bishop said about the nature of their relationship. She had every right to say that she wanted you out of her home.”
