A friend of two brothers charged with the murder of a woman had earlier assaulted her with "windmill punches" and stamped on her body, a jury was told.
Siblings Nicholas and Stuart Curtis are on trial for the killing of Glenda Jackson in a communal hallway outside flats at Grayson Mews, in John Street, Birkenhead.
It is alleged the 44-year-old victim was repeatedly stabbed in a frenzy hours after telling police she had been attacked and suffered homophobic abuse.
Earlier, the brothers and pals had been on a boozy night out at Seamus O'Donnells pub in Birkenhead, before the group decided to go back to one of the accused's flats.
The friend, James Lunt, who appeared in court as a witness, and is not one of the accused, had been drinking Stella lager and shots of amaretto, spending more than £100 in the bar on the evening of September 29, last year.
He said he'd downed up to eight pints and some shots on that night, adding he was a "fast drinker".

Giving evidence today at Liverpool Crown Court, he was asked about a confrontation between him and the deceased outside Nicholas Curtis' flat where the group had gathered.
The jury was told that Ms Jackson was "moaning as we were being loud coming in" and said he "thought I told her to shut up and calm down - she was equally as loud".
Mr Lunt mentioned hearing the victim on the phone to the police and made the decision to leave the flat and go home with his then-girlfriend Dionne Kane.

Anthony Berry, QC, representing Nicholas, quizzed Mr Lunt how he had injured his hand to the extent that he thought he may have broken it and was "in agony."
Mr Lunt said he'd had a bust-up with bouncers outside Seamus O'Donnell's because they'd asked him to leave because he was drunk.
Outraged and grabbing one doorman by the collar, he replied: "I've spent over £100 in this bar."
But Mr Berry suggested to Mr Lunt that he had told Ms Jackson to "chill, mate" after she complained about the noise, before she replied, "I'm no mate, I'm a bird."
"No you're not, you're a bloke," was the response, Mr Berry claimed.
Mr Berry said: "She threw a punch at you."
He added: "You punched her many times. She fell to the floor, you kicked her and almost certainly stamped on her."
But Lunt responded "She didn't punch me.
"That's not true. That's not right."

One barrister enquired why Mr Lunt appeared to adopt a series of alias names, calling himself Jay, James Lewis, and even "Journey - a reference to his previous habit of "taking a lot of drugs."
After Ms Jackson's killing, police came to talk to Mr Lunt and arrested him for actual bodily harm, relating to the assault outside the Grayson Mews flats.
Detectives made it clear to Mr Lunt that he was NOT being detained for her murder, they assured him.
He was cautioned, but when asked questions about Ms Jackson he stayed silent, and repeatedly gave a "no comment" to everything he was asked.

That tactic was advised by his lawyer, Mr Lunt added.
Nina Grahame, QC, defending Stuart, stated: "You[Mr Lunt] assaulted Glenda Jackson, with windmill punches ...arms going round and round, with repeated punches, kicks and stamps that you had to be pulled away from her."
Officers attended following Ms Jackson's call to the police, but when the cops left the scene at 2.35am, Ms Jackson “got angry”, armed herself with a knife and a hammer, and began damaging a white Mercedes Sprinter van parked outside, which belonged to Nicholas Curtis.
Alerted by loud bangs, Curtis bolted out of the flat barefoot, wearing his boxer shorts and a jumper, and went to investigate what he thought was his van being broken into.
At some point in the next few seconds, there was an altercation between Curtis and Ms Jackson which left her dying in the communal hallway.
Both brothers, of Grayson Mews, deny murder.
The trial continues.
