Darren Pencille, 36, stabbed Lee Pomeroy in the neck and upper torso 18 times. He was jailed for life at the Old Bailey today after he was convicted of murder
A train passenger who brutally stabbed a father in front of his son was a paranoid schizophrenic who smoked cannabis and saw a psychiatrist the day before the murder.
Darren Pencille, 36, knifed 51-year-old Lee Pomeroy 18 times in a ‘savage and unrelenting’ attack on a train from Guildford to London Waterloo on January 4 this year.
Cannabis addict Pencille, who was diagnosed with paranoid schizophrenia in 2003, was this afternoon jailed for life at the Old Bailey and will serve a minimum of 28 years.
Today it can be reported for the first time he was seen by a psychiatrist 24 hours before murdering Mr Pomeroy – but had been certified as ‘no risk to himself or others’.
The consultant forensic psychiatrist who saw Pencille said he had been admitted to River House Medium Secure Unit in March 2015 where he was observed to be ‘confrontational and agitated’ if he did not get his own way.
He was also said to be ‘angry and threatening’ when his behaviour was challenged.
Pencille has been in contact with mental health services since 2003, but despite his violent tendencies and mental health problems he was deemed to have been ‘no concerns of risk to himself or others’ during his final appointment on January 3 – the day before he murdered Mr Pomeroy.


Darren Pencille, 36, was convicted of murdering Lee Pomeroy on a Guildford to London train in front of his 14-year-old son
Months earlier he had told a hostel worker: ‘I’m going to kill you you c***’.
Pencille refused to take medication after his diagnosis in 2003 – instead choosing to treat himself by smoking super-strong cannabis each day.
The Old Bailey had heard how 5ft 10in tall Pencille had a history of violence, having previously stabbed a flatmate in the neck over a minor disagreement in 2010.
He had also threatened to kill a staff member at a mental health hostel in June last year.
A jury deliberated for 19 and a half hours to find Pencille, of no fixed abode, guilty of murder.

The violent criminal past of Darren Pencille, 36, was revealed by MailOnline today in an extraordinary gangland video (pictured in 2009) as he was found guilty of murder
The court heard Pencille’s criminal record contains 14 convictions for 19 offences which also include burglary matters, witness intimidation and possessing a firearm.
He was a lieutenant in the South Man Syndicate [SMS] crew in London – whose members have terrorised Tooting, Streatham and Thornton Heath since the 1990s.
One fellow gang member who knew him well told MailOnline: ‘He smoked weed constantly and was a complete psycho. I feel so sorry for the man he killed and his son’.
