Doctor who disguised himself to poison his mother's partner with fake Covid jab jailed for 31 years

Wednesday, November 6, 2024 - A British doctor who wore a disguise when he injected his mother's partner with a fake Covid-19 booster in a dispute over inheritance has been jailed for 31 years.

Dr Thomas Kwan, 53, admitted trying to killing Patrick O’Hara in an extraordinary plan that left the 72-year old with a rare flesh-eating disease.

He had initially denied attempted murder, but changed his plea after he heard the prosecution open the case against him at Newcastle Crown Court last month.

On Wednesday, he was sentenced to 31 years and five months behind bars by Judge Mrs Justice Lambert, who said: “It was an audacious plan to murder a man in plain sight and you very nearly succeeded in your objective.’’

At a previous hearing, the victim said the fake vaccination caused intense pain, making it seem as though his arm was on fire, and that he felt he should have died.

Mr O’Hara needed weeks of hospital treatment after developing a flesh-eating disease which required plastic surgery and he said the attack left him “a shell of an individual”.

Kwan, who was obsessed with money and developed a deep knowledge of poisons, planned his murder bid for months by writing fake letters, supposedly from the NHS, offering Mr O’Hara a home visit in January this year.

The married 53-year-old was motivated by greed after finding out that his mother, Jenny Leung, had made a will which allowed Mr O’Hara to stay in her home should she die before him. The couple have split up since her son’s attempt on his life.

Peter Makepeace KC, prosecuting, said at a previous hearing: “The motive for this attempt to kill was to remove an impediment to his inheritance.”

Kwan refused to tell police which poison he had used as medics battled to save Mr O’Hara.

His victim had responded with stoicism to his physical suffering, the court heard, but he has since developed post-traumatic stress disorder.

Officers scoured CCTV and were able to track Kwan, still disguised as a nurse, back to a city centre hotel and then to his home in Ingleby Barwick, Teesside.

In his garage they discovered an array of dangerous chemicals which the GP had amassed. On his computer, they found instructions on how to make the chemical weapon ricin.

It was first thought he had used ricin on Mr O’Hara but a poisons expert said iodomethane, which is used in pesticides, was more likely.

During the trial last month, Paul Greaney KC, defending, said the GP was previously of positive good character, and had “ruined his life”.

He described Kwan’s disguise, when he passed himself off as a nurse, as “amateurish” and “clumsy”.
