The girlfriend of Nicholas Dill told a jury that Andre Hypolite stabbed him in the back and chopped her in the head after a drug-fuelled sex session turned violent.

Recalling the alleged murder of Mr. Dill on Boxing Day 2004, Stacey Pike said Hypolite knifed him after he backed out of performing a sex act on him.

"I saw that blade and Nicky's whole body just came forward. I don't know if Nicky made a sound. I screamed and Nicky said 'I'll do whatever you want. What do you want'?" she told Supreme Court yesterday.

"Andre stood in front of us on the bed. Both of us was looking up at him. I was saying 'Andre, stop, what do you want?' He was standing there with this big knife going 'what, what?' – just screaming in our faces."

Opening her graphic account of events, which at times saw her break down in tears, Ms Pike, now 37, said she had been in a relationship with Mr. Dill, 43, for three years.

They lived together at his home – described by a Police officer in testimony earlier this week as a "dilapidated shack" in Pearman's Hill, Warwick.

Ms Pike said she and her boyfriend took drugs during their relationship, and she awoke around 2 a.m that Boxing Day to find Mr. Dill and another man named "Shaki" smoking crack cocaine at their home.

She went out to purchase more drugs, and encountered Hypolite nearby on Khyber Pass. Ms Pike told the jury she knew him from primary school, and he had been visiting her home since November 2004.

On five previous occasions since November, she had given Hypolite oral sex – with Mr. Dill present – in exchange for Hypolite supplying them with drugs.

Hypolite said he had drugs on him on this occasion and accompanied Ms Pike back to the Pearman's Hill residence.

"Shaki" eventually left, leaving Ms Pike, her boyfriend and Hypolite in the bedroom where they all smoked crack cocaine. According to her, Hypolite laid a knife down in front of her DVD player.

"It was not one of those bread knives. It was a really long-bladed knife. I remember commenting about the size of it," she told the court.

According to her, Hypolite then undressed and she performed oral sex on him in between smoking crack cocaine. Next, she said, Mr. Dill let Hypolite perform oral sex on him.

"I had known Nicky for three years. I had never seen him do anything with a guy before," she told the jury.

She continued to detail how Mr. Dill then agreed to let Hypolite give him anal sex, but "froze" at the last moment and said "I can't do this."

Ms Pike described how she saw Hypolite step behind Mr. Dill and knife him in the back. Both men tumbled off the bed as a fight broke out between them.

Ms Pike said she went to go to get a machete, which was in the corner of the room because she and her boyfriend did landscaping work.

"By the time I got to the foot of the bed to get up, I felt I got hurt. I felt a bang on the top of my head...Andre was standing right next to me with the knife in his hand, and he had just hit me in the top of my head with the knife," she said.

As she continued toward the machete, she claimed Hypolite threw "a big, huge TV" at her, but it didn't hit her.

She is due to continue her evidence today.Earlier yesterday, the jury heard from Lisa Caines, 45.

She told them she had known Hypolite for eight months prior to the events in question. They had been in a sexual relationship and he had lived with her at her home in Raynor's Drive, Southampton, but the relationship had ended by that point.

She described how he visited her home late on Christmas Day and talked to a friend of hers who was there, called Ryan Furbert and also known as Murphy.

Ms Caines said Hypolite had two carving-type knives with him, which he pulled out during the visit. He then left with a machete belonging to Mr. Furbert / Murphy.

Ms Caines went on to tell how she saw Hypolite on Horseshoe Road early on Boxing Day, while it was still night time, and again later that morning when he returned to her home.

"He wanted me to let him in. I told him 'no'. He didn't have a shirt on. He had blood marks on him like someone cut him up. He had pants on, blue jeans. He looked like he was terrified," said Ms Caines.

She described how Hypolite walked away and asked her to phone his brothers, but she didn't know who he was referring to.

Under cross-examination from defence lawyer John Perry QC, Ms Caines denied that she was under the influence of drugs as she was giving evidence, despite admitting to 20-year addiction to cocaine and heroin.

She amended her previous evidence, saying Hypolite had not two but three knives on him during his Christmas Day visit. The defence lawyer put it to her that she never saw him with any knives, but she responded: "Andre always carried a knife. Always."

She denied Mr. Perry's further suggestion that she let Hypolite in on his Boxing Day visit to her house, either carrying him or assisting him inside and then cleaning the blood from his wounds. She also refuted his further claims that Hypolite asked her to call the Police and that she hid him in her house, behind a bedhead in her bedroom.

Ms Caines expressed annoyance throughout Mr. Perry's cross examination.

"This is irritating. I have no reason to lie. This situation is nothing to do with me. Andre has inflicted this on me. Why would I make up stories? I didn't ask for this," she complained.

Hypolite denies murdering Mr. Dill and wounding Ms Pike with intent to cause her grievous bodily harm, and the case continues.
