The widow of a man stabbed to death on a train wept as footage showed the moment he was knifed 18 times during a “relentless” attack.
Darren Pencille, 36, allegedly killed 51-year-old Lee Pomeroy in a “savage” onslaught on board the Guildford to London Waterloo train on Jan 4.
Mr Pomeroy, who died on the eve of his 52nd birthday, was on his way to the capital with his 14-year-old son for a day out.
The boy witnessed the attack.
The Old Bailey has heard how an argument broke out after Mr Pencille made a “rather snide” remark as he jostled past the Pomeroys moments after getting on the train.
According to one account he said: “Ignorance is bliss.”
As the father remonstrated with him, Mr Pencille whipped a knife out of his jacket pocket and stabbed Mr Pomeroy in the neck, jurors were told.
Mr Pencille got off at Clandon, where he was picked up by girlfriend Chelsea Mitchell, 28, who is accused of ferrying him away from the scene, helping him change his appearance and carrying out internet searches into the killing.
Mr Pomeroy died a little over an hour later after suffering the fatal wound to his neck along with another eight wounds to his torso and further cuts to his arm, hands and thigh, all inflicted in less than 30 seconds.
Jurors were yesterday taken through various CCTV clips piecing together events leading up to the fatal stabbing.
Some members of Mr Pomeroy’s family, who were seated in the public gallery, walked out before footage of the stabbing was played.
The IT consultant can be seen arriving at the station with his son.
Mr Pencille arrived a few minutes later.
When their train pulls up they get on through separate doors but cross paths in the aisle when they turn in towards each other.
Mr Pomeroy remains standing as Mr Pencille walks by and both men exchange looks before the IT consultant takes his seat, jurors heard.
Following a brief exchange, Mr Pomeroy can be seen on the carriage’s CCTV to walk after Mr Pencille.
Jurors were played footage of the two men walking through the carriage into the adjoining one before they stop and continue arguing in a standing area.
Mr Pomeroy, at times clutching a piece of paper which he eventually places in his pocket, can variously be seen clinging on to the metal poles to keep his balance, pointing back over his shoulder and holding his palm up towards Mr Pencille.
Other passengers described hearing him pressing for an apology, saying: “You shouldn’t have humiliated me in front of my kid.”
Mr Pencille can then be seen pulling his phone out and holding it up to his ear – a call jurors were told was to Ms Mitchell – in which he warns: “I’m going to kill this man. He’ll be dead.”
Within 10 seconds, Mr Pencille had pulled out a knife.
Jacob Hallam QC, prosecuting, told jurors the blade is visible on screen before a bloodied Mr Pomeroy walks back down the carriage following a scuffle.
“So, we are dealing with an incident that lasts for about 25 seconds,” he said to DC Marc Farmer, a British Transport Police officer.
“And the jury know that in that 25 seconds Lee Pomeroy sustained 18 knife injuries.”
The wound to Mr Pomeroy’s neck opened his jugular vein and carotid artery. As Mr Pomeroy staggers away from Mr Pencille he collapses into a seat and can be seen panting heavily.
Mr Pencille jumped off the train moments later when it stopped at Clandon.
He was picked up soon after by Ms Mitchell and taken down to Chichester later that evening, where she bought him a set of clippers and razors.
Mr Pencille, of no fixed address, denies murder while Ms Mitchell, from Farnham in Surrey, denies assisting an offender.
The trial continues.
