A dad-of-three named his alleged killer with his dying breaths after being stabbed through the heart, a court heard.
Jamie Simmons, 29, was knifed after a row over a remark about his girlfriend escalated, jurors were told.
A jury heard that “as he weakened through blood loss and sadly with only about 15 minutes to live”, Mr Simmons identified his alleged attacker.
As he lay dying he allegedly said: “Kieron stabbed me. Why would he do that? Why would he do that?”
Kieron Nicholson, 29, is on trial accused of murdering Mr Simmons, who turned 29 a week before his death in Maidstone, Kent, in May. Mr Simmons’ daughter was born just weeks before he died.
Nicholson denies the charge.
Maidstone Crown Court heard an argument began when Mr Simmons clashed with a friend of Nicholson, Jack McCann, over a remark made to his partner Charlotte Muddiman about “sorting her out”.
Prosecutor Ahmed Hossain QC said: “During a discussion, Mr Simmons said he had to go and sort out his children and it was then that Mr McCann made an ill-judged comment, to the effect of saying ‘you go and sort your kids out and I’ll sort your missus out’.
“That caused offence to both Mr Simmons and Ms Muddiman. Jack McCann tried to say he was only messing about but it caused a confrontation.”
That comment led Mr Simmons to punch Mr McCann in the face and then head-butt him, causing his nose to split and bleed heavily, the jury heard.
Mr McCann’s remark was made outside the flat of Tyra Cooper, the on-off girlfriend of the defendant.
After going inside the flat, an irate Mr Simmons was said to have attacked Mr McCann and was then allegedly stabbed by Nicholson.
Mr Hossain added: “At this point the confrontation had nothing to do with Nicholson. Mr McCann then went into the flat of Tyra Cooper to get something.
“Ms Muddiman saw this and pushed him up against a wall and it was at this point Nicholson came into the kitchen and grabbed a knife and started stabbing at Jamie Simmons.
“Tyra Cooper was heard to shout ‘Get the f*** out of my flat’.”
Nicholson is then alleged to have grabbed the steak knife before shouting: “Get the f*** out or I will stab you”. As Ms Muddiman tried to shield her partner, she received two superficial cuts to her arm.
She later told police that Nicholson had been holding the knife in his right hand and “making jabbing motions” towards Nicholson.
Mr Hossain said she tried to usher Mr Simmons out of the flat before noticing a red stain on his left chest and “realised he had been stabbed twice”.
The prosecutor said another neighbour, alerted by the noise of the argument, then began recording the incident on a mobile phone.
He told the jury: “You will hear Jamie Simmons in his dying moments, saying: ‘Kieran, Kieran you mother of c**** why have you got to get involved?'”
Others also heard the threats which the prosecution say showed Nicholson had “enough of his friend Jack McCann being beaten up and on the receiving end” and stormed into the kitchen to “put an end to the altercation”.
Nicholson is alleged to have then fled through a window only to be stopped by a neighbour and held until police arrived.
At the time, Mr Simmons and Ms Muddiman were living together in a flat in the nextdoor block to where the attack took place.
A pathologist is expected to tell the four-week trial that “severe force” had been used to plunge the knife into his heart which was “equivalent to a firm punch”.
The jury is due to travel to the estate where the killing took place to examine at the scene.
Due to coronavirus restrictions they were urged by the judge to wear masks, gloves and carry hand sanitisers.
The trial continues.
