A woman told a jury how she battled in vain to save a man allegedly knifed to death by his girlfriend.

Prosecutors say Andrina Smith, 26, stabbed Edward Allan (Sleepy) Dill after he slapped her during an argument at her home in Cedar Park, Devonshire.

Joezine Butterfield-Wolffe heard the dispute in the early hours of October 16, 2006, and went outside to find Mr. Dill, 35, bleeding from a wound to the neck.

"He was holding the left side of his neck and a cell phone in his right hand and I heard him on the cell phone telling someone that 'Andrina killed me'. I could tell it wasn't a two-way call, it was like he was leaving a message," she told Supreme Court.

"I shouted to him and said 'I'm here, I know' and I told him my daughter had called 911. When he turned to me I could see blood on his face, his arms and his shirt. The cell phone dropped on the ground and I could see blood."

Ms Butterfield-Wolffe broke down in tears as she gave a graphic account of how she tried to stem the blood pouring from Mr. Dill. Her evidence left several members of the jury visibly shaken.

She also told how, as she waited for the ambulance to arrive "he kept telling me he's dying — 'she f*****g killed me.' I told him he's not dying, the ambulance is on its way, to hold on, to keep thinking of his children to give him strength."

According to her, the Police arrived before the ambulance did.

"They said 'it's Allan Dill'. That was the first time I had heard his real name. They just walked away, just left him there," she claimed.

She went on to describe how Smith came outside the apartment and allegedly attacked her bleeding boyfriend, the father of her one-year-old baby.

"She came to pounce on him, to fight him. She came over to him to beat on his chest," she claimed, telling the jury she tried to fight her off while still helping Mr. Dill.

Senior Crown counsel Carrington Mahoney told the jury in his opening speech that Smith had plunged a knife through a door and into Mr. Dill's neck after he gave her a "slap" inside the apartment.

Ms Butterfield-Wolffe told the panel Smith had a swollen face, said that Mr. Dill had punched her, and repeated "look what he did to my face" as she came at him outside.

According to the witness, she responded by telling Smith: "What about f*****g you? He's dying. There's nothing wrong with you."

She also claimed Smith told her own grandmother, Patricia Francis: "I'm going to f*****g get you, you want to take his side."

Later, she said, Smith was restrained by two or three Police officers who put her on the ground and handcuffed her.

Defence lawyer Charles Richardson put it to Ms Butterfield-Wolffe that Smith was "distraught", and put her hands on Mr. Dill's chest saying: "I didn't mean it, I didn't mean it, but look what you did to me."

Ms Butterfield-Wolffe denied this.

Asked about the relationship between Smith and Mr. Dill, the witness said they would have arguments in the early hours of the mornings that woke her up.

"They always had an issue about infidelity," she said, going on to explain she meant infidelity on the part of both.

She said she never heard physical fighting going on in Smith's apartment but "very loud, verbally abusive arguments".

Smith denies murder, and the case continues.
