A woman stabbed her boyfriend 24 times during an argument, a murder trial jury heard.
Michelle Mills left Edward Miller, 20, bleeding to death on the living room floor of their home in Scalford, near Melton.
The jury at Lincoln Crown Court was told she stabbed him repeatedly with a kitchen knife using such force that the blade broke away from the handle.
The court was told mother-of-two Mills (31), who denies murder, then dialled 999.
Paramedics arrived at the scene in King Street within minutes and Mr Miller was taken to Nottingham's Queen's Medical Centre in an ambulance driven by a police officer, while the two paramedics continued efforts to revive him.
He was pronounced dead soon after arriving at the hospital.
Yvonne Coen QC, prosecuting, said the couple, who had been in a relationship for two years, often argued but were described as "smitten" with each other.
Earlier in the evening, they were seen being affectionate with each other at a Bonfire Night party at the Kings Arms, in the village.
However, back at their home they argued so loudly a neighbour turned up her television to drown out the sound.
Miss Coen said: "The neighbour heard banging and crashing which seemed like they were fighting and furniture was being knocked over.
"Mills was heard crying."
Just after 1am, Mills made a 999 call telling the operator, "Me and my boyfriend just fell out and I've just stabbed him. He's all over the place."
Paramedics arrived within minutes to discover Mr Miller bleeding heavily from multiple stab wounds.
Mills was arrested and told police, "I grabbed the knife and I went mental. I don't know how many times I stabbed him".
Miss Coen told the jury "There is no dispute that Ms Mills stabbed Eddie Miller and that she caused his death. She accepts she is guilty of causing his death.
"The prosecution suggests that Ms Mills, in drink, became aggressive and lost her temper with her boyfriend.
"She was apparently thinking fondly of her ex during the row with Eddie Miller and texted him in affectionate terms.
"After Eddie, on her account, had grabbed her and pushed her on the sofa she got away from him. It could have stopped. All he wanted to do, it seems, was to sit having a drink. It would seem that she wasn't going to leave it there.
"She wasn't going to let him ignore her so she took it to the next level by taking a knife to him repeatedly, perhaps to punish this young man for what may have happened between them before, but clearly to hurt him very severely and during the course of it she actually broke the knife. If that is right, this is a plain case of murder."
The jury was told the couple had moved in together just two months earlier after previously living at Mr Miller's mother's home in nearby Eastwell.
Miss Coen said: "This was his first grown-up relationship with a woman. She was an older woman and a mother of two."
The couple's next door neighbour Geraldine Paynter told the jury she was kept awake by arguments from their property.
Ms Paynter said that on the night Mr Miller died she heard him screaming at the top of his voice, "It's you. It's your fault."
Later, she said she heard Mills repeatedly shouting, "get off me" before hearing her sobbing uncontrollably.
Pathologist Prof Guy Rutty, who carried out a post-mortem examination on Mr Miller's body, told the jury that death was due to stab wounds to the chest and abdomen.
He said the injuries on Mr Miller's body included 24 incised wounds, together with a number of other injuries.
One of the stab wounds damaged a major vein, while his lung was also punctured.
Another blow damaged the right shoulder bone.
Prof Rutty said: "He has been stabbed to the front and back of his body. Considering the injuries I found to his hands he will have grabbed the blade in an attempt to defend himself from the attack."
Blood tests on showed he had 297 mgs of alcohol per 100 mls of blood – almost four times the legal limit for driving.
Prof Rutty said: "It was a significant amount of alcohol.
"If it was somebody not used to alcohol they would be approaching the point where they would be losing consciousness."
Mills, of King Street, Scalford, denies murder on November 6 last year. The trial continues.
