A new documentary sheds light on the horrific lengths an evil GP went to in a plot to murder his mother's partner.

In a case that prosecuting barrister greedy , from Teeside, disguised himself as a community nurse while carrying out his malevolent plan on January 22, 2024.

Under the pretence of carrying out a home visit for a COVID-19 booster vaccination, even going as far as to fake documents and wear a wig and fake facial hair, Kwan managed to get inside the home of his mum's partner of 20 years,

As is explored in tonight's Channel 5 documentary, Inheritance: Murder in the Family – The Thomas Kwan Affair, it was then that

Kwan's relationship with his mother, Jenny Leung, had been strained for some time, and things reached boiling point when he learned Jenny had granted Patrick a life interest in her property, which Kwan, 53, felt was getting in the way of his own inheritance.

Patrick, then 71, began to suffer excruciating pain immediately after receiving the injection and woke up the following day with blistering on his arm. Doctors subsequently diagnosed Patrick with necrotizing fasciitis, a potentially fatal flesh-eating disease. After multiple surgeries and several weeks spent in intensive care, Patrick thankfully pulled through, but has since suffered PTSD.

Kwan, who pleaded guilty to attempted murder halfway through his trial at Newcastle Crown Court, was handed a and ordered to serve at least 31 years and five months. While jailing him in November, Judge Mrs Justice Lambert told the court that she had "no doubt" that the £140,000-a-year GP was motivated by "financial gain".

Mrs Justice Lambert told Kwan: "Your intention of visiting the home was to administer a lethal injection of poison to Mr O'Hara on the pretence of administering a Covid booster. It was an audacious plan to murder a man in plain sight and you very nearly succeeded in your objection.

"You were in the home of Mr O'Hara for 40 minutes and for some part of that your mother was also present and you took her . Extraordinary though it seems, so trusting were they that neither recognised you under your disguise."

She continued: You were certainly obsessed by money and more particularly by money which you considered yourself to be entitled. I have no doubt that the reason why you tried to kill Mr O'Hara was for financial gain.

"You knew your mother had left the house to her children but you also knew she had changed her will to give Mr O'Hara a life interest in the house. By killing him you removed the obstacle which lay between you and your recovery of your share of the property following your mother's death."

Kwan's wife previously told the how her husband's behaviour had changed just before 2023, with his scheming affecting his sleeping patterns. Although Kwan had amassed a horrifying collection of poisons, including arsenic, liquid mercury, sulphuric acid and castor beans for the chemical weapon ricin in the garage, his wife was left in the dark.

His wife, who shares an 11-year-old son with Kwan, said: "I knew nothing about this. I know what he did was bad. I think he intended to harm, not kill. Last November/December, he started to change, he was not normal. He was very nervous, he was sweating at night. He was not sociable, he liked to work but he did not have any social life, he is a very private man.

"Our married life was very, very happy, he was a very good doctor and happy with his patients. I think he had a mental illness but as a GP, he did not want to book an appointment to seek help. He did not escape, he kept everything he used, it was all there for the police when they came to arrest him. It does not make sense."

Inheritance: Murder in the Family – The Thomas Kwan Affair airs on Channel 5 on Monday March 3rd at 10pm.
