The father of a British student who killed himself after a chef dubbed the 'poison killer' sold him a suicide kit says there is 'no justice' for his son - amid fury he will not face charges in the UK.Thomas Parfett, 22, died in Sunbury-on-Thames, Surrey, in 2021, after taking the lethal substance which he bought online from Kenneth Law, who admitted charges of aiding suicide on Friday. Law, 60, appeared in court in Ontario, Canada, after selling 1,200 packages containing the toxic chemicals across 40 countries, including the UK. He formally entered his guilty pleas to a total of 14 counts, all relating to Canadian victims.An investigation by the National Crime Agency (NCA) into Canada-based websites selling substances to assist with suicide found that 286 individuals received packages in the UK, leading to 112 deaths. But despite prosecutors in Ontario bringing Law to court, the NCA and Crown Prosecution Service (CPS) have written to the bereaved families to tell them they would not be seeking to extradite Law to the UK after legal proceedings in Canada had concluded. This is due to the potential for Law to challenge the extradition after being convicted of similar offences in Canada. Kenneth Law, 60, (pictured) who is linked to the deaths of 112 people in the UK after selling them packages containing lethal substances, will not face justice in the UK In a letter sent on Thursday, the NCA and CPS agreed Law was to be 'sentenced for the full extent of his offending within a single sentencing process in Canada.'It was a decision, they said, that was reached 'only after detailed consideration of all available options.'Now, Thomas's father, David Parfett, 58, has spoken of his anger at the decision to not extradite Law to Britain to face charges.Mr Parfett said the ruling was 'done to me, not with me,' and in 'no way' brings justice to his son. He said: 'I am angry but not surprised. For months, we have been told that the system is working and that existing measures are enough. They are not.'He's not ever been charged with a crime against Tom. 'Yet this is the man that made £50 from selling my son a substance to kill himself, probably having persuaded him to do so, and yet he will never face charges.'It doesn't send the right message to other people that are doing the same thing, typically using internet sites.' Pictured: Tom Parfett, who died aged 22 after taking his own life in Sunbury-on-Thames, SurreyMr Parfett, a data architect from Twickenham, London, said Law's actions have caused 'horrendous damage' to his family, and added his son would 'very likely still be here' if not for Law trying to make money.He also expressed concerns that Law's sentencing will not be long enough after Canadian authorities dropped more serious murder charges. The maximum sentence for aiding suicide in Canada is 14 years – the same as for encouraging suicide in the UK.It is understood that the sentence is likely to be more than 14 years because of the number of victims and the nature of the offences.Mr Parfett said: 'I hope he is remorseful of the fact that he has exchanged lives for money. But I've not yet seen that remorse, and to me he would still remain a danger after the sentencing.'I hope that he has had the chance to understand the damage he's caused. 'I'd like to be in a position to be able to forgive him. I'm not today, but I'd like to be in a position to forgive him.'I certainly couldn't do that today, because, again, I'm not convinced he understands. But I'd like to think that he thinks about Tom sometimes.' Law sold 1,200 packages containing lethal substances across 40 countries, including the UKMr Parfett called for tougher internet regulations and changes to be implemented to make accessing poison online more difficult.He said Thomas, who was a philosophy student at the University of St Andrews, was able to access an online 'suicide' forum before he died, where he was encouraged to end his life by other users. He added that because of 'nefarious' websites being run from the UK that those such as Law are able to sell their harmful products. Mr Parfett said: 'There's others who should be prosecuted and nobody is taking the action.'We actually need to look at this seriously. We need to make sure that we change our processes. 'For instance, when you investigate a suicide of a young man like Tom, it should be a matter of course to capture the digital footprint.'Mr Parfett has since joined the families of other victims to demand a public inquiry to establish the 'lessons' from deaths such as his son's.He said: 'We accept things on the internet that aren't acceptable on the high street. Where else would you be able to provide somebody with detailed instructions of how to kill themselves? Pictured: Aimee Walton from Southampton, who died in 2022 aged 21. Her sister said that 'doors have been shut' for families seeking justice 'Would you walk into a bookstore to do that? I think that bookstore would be prosecuted, and yet we allow this to happen on the internet.'Then we get ourselves into a regulatory twist about how to deal with it, while people continue to die – it's just not good enough.'It's a complex issue, and that's why it needs the public inquiry – because you have to bring people together.'In total, Law sold 1,200 packages to 40 countries across the world from Canada-based websites, with 286 people in the UK receiving products.Some 330 products were sent to the UK, one to the Isle of Man and 12 to Ireland.After his Canadian convictions, British prosecutors described Law as a 'serial offender who callously exploited many vulnerable and innocent people exchanging their lives for his financial gain'. Among Law's British victims include 21-year-old Aimee Walton from Southampton, who died in 2022. Her sister, Adele Zeynep Walton, said the decision to not extradite Law has meant 'doors have been shut' for families seeking justice. She said: 'The question for our own country is simpler still: who here will examine how the British state let this happen, and what it will do so that no other family goes through it?TikTok star Imogen Nunn, who was known as Deaf Immy on social media where she highlighted hearing and mental health issues, died aged 25 in Brighton 'A foreign sentencing hearing cannot answer that. Only a statutory public inquiry can.'This week, the harrowing details of the deaths of Law's British victims was heard in court. It was heard how Tom Windsor told police he used the substance sold by Law and was later found by emergency services unconscious with his phone still in his hand connected to the 999 call.Windsor told the call operator he did not want to die and appeared to be panicking before paramedics arrived 26 minutes later.Another British victim, a 43-year-old woman, died in July 2021 after her four-year-old daughter asked the woman's husband where she was.The court heard he took her to the living room, where they found his wife 'slumped over their daughter's dollhouse'.Another of Law's victims died 12 days after a visit from South Wales Police, who were performing a wellness check when she refused to give officers the poisonous substance.Danielle Cornish, 29, told officers she had no intention of killing herself and police took no action. Canadian Jeshennia Bedoya Lopez (pictured) was 18 when she died by suicide. Law's alleged victims included teenagers and young adults in their 20s and 30sHowever, she died shortly thereafter after becoming unconscious during a call to emergency services, in which she admitted taking the product sold by Law.It was also revealed that a number of Law's British victims had a history of mental health issues, however, one man named Oliver Wade, who had no record of physical or mental health issues, killed himself three days after his mother died of cancer.Michael Dunham, Neha Raju and Imogen Nunn were named as other British victims, as well as an unnamed student that allegedly died after buying products from Law's company. Andy Burrows, chief executive of Molly Rose Foundation, said: 'Bereaved families have been campaigning tirelessly to hold Kenneth Law to account in the UK and to be told he will not be prosecuted here on the eve of his court case in Canada is a bitter blow. 'Families up and down the country have been impacted by Law's crimes and should have the right to full justice in the UK. 'As long as the pro-suicide forum remains online, and while this substance is available in the UK and across borders, more vulnerable people are at risk.' Law, who lived on the outskirts of Toronto, is alleged to have operated a website selling the toxic substance for two years. He is accused of setting up an account on a forum and naming himself 'Greenberg,' posing as a retired New York medical examiner. He has also been investigated by police in the United States, Italy, Australia and New Zealand. Journalists confronted Law about his activities in 2023 and he was arrested a week later, remaining behind bars since then.
