In a twisted plot that seems straight out of a thriller, a British doctor disguised himself as a nurse and attempted to murder his mother’s partner with a fake COVID-19 shot. The story, which is already sending shockwaves across the UK, centers on a heated family inheritance dispute and an act so cold-blooded it has left the public reeling. Let’s dive into the details of this sinister case that unfolded in Sunderland, England.

How a Family Dispute Led to Attempted Murder

Meet Thomas Kwan, a 53-year-old family doctor from Sunderland. On paper, he seemed like your average medical professional, but underneath his calm demeanor lurked a deadly obsession: greed. The source of his twisted plot? An inheritance dispute with his mother’s long-time partner, Patrick O’Hara, a man who had been part of their lives for over 20 years.

When Kwan discovered that his mother had left her house to O’Hara instead of him in her will, something snapped. His medical expertise and access to poisons became the deadly tools for a plan that would almost cost a man his life. In an attempt to eliminate O’Hara, Kwan went to shocking lengths, donning a disguise and forging letters to orchestrate an elaborate ruse.

Now, we all know doctors have a duty to save lives, right? Well, not Thomas Kwan. Instead of using his knowledge for good, Kwan put on a wig, a fake goatee, and a medical mask, passing himself off as a nurse to administer what O’Hara believed was a COVID-19 booster shot. It’s the kind of plot twist that leaves you shaking your head.

With the disguise in place, Kwan showed up at O’Hara’s home for a “medical check-up” he had cleverly arranged. O’Hara had no reason to suspect the man in front of him—after all, a masked medical professional showing up for a booster jab had become routine during the pandemic. But what he didn’t know was that Kwan’s syringe wasn’t filled with any life-saving vaccine. Instead, it was a lethal concoction designed to inflict unimaginable pain and suffering.

A Life-Changing Infection

Shortly after receiving the injection, O’Hara fell seriously ill. He was rushed to the hospital, where he handed over the suspicious letters Kwan had sent him—letters that immediately raised red flags with hospital staff. Realizing the documents were forged, the hospital contacted police, and what began as a routine visit turned into a full-blown criminal investigation.

O’Hara didn’t just fall ill; he developed necrotizing fasciitis, a horrific flesh-eating infection that nearly cost him his life. Multiple surgeries, including skin grafts, were needed to combat the extensive damage caused by the toxin. The extent of his suffering cannot be overstated. A flesh-eating bacteria? It’s a nightmare come to life.

A Sinister Plot Unveiled

As the investigation progressed, police quickly honed in on Kwan as their prime suspect. It didn’t take long to piece together the grim picture. Kwan had driven from his home in Ingleby Barwick to a hotel in Newcastle the morning of the attack, taking extra steps to conceal his identity by putting fake plates on his car.

When police raided Kwan’s home, they discovered what can only be described as a would-be murderer’s playbook: a “poisoner’s handbook” and guides on how to carry out the perfect crime. His computer contained files on lethal poisons and how to avoid detection, leaving no doubt that this attack had been meticulously planned.

Despite the overwhelming evidence, Kwan didn’t fully cooperate with authorities. Though he pled guilty to attempted murder, he refused to disclose the specific poison he used, leaving medical professionals to fight an uphill battle as they tried to treat O’Hara without knowing exactly what had been injected into him.

Kwan Faces Sentencing

Kwan’s despicable actions caught the attention of the media and the public alike. Detective Chief Inspector Jason Henry didn’t mince words, describing Kwan’s actions as “utterly despicable.” Using his knowledge as a doctor, Kwan duped O’Hara into thinking he was getting a legitimate COVID-19 booster shot, when in fact, he was injecting him with a deadly substance.

In court, prosecutors made it clear that Kwan’s motive stemmed from nothing more than greed. He was enraged that his mother had chosen to leave her house to O’Hara instead of him. Prosecutor Peter Makepeace succinctly summed up the situation: “Sometimes… the truth really is stranger than fiction.”

Though Kwan’s attempt on O’Hara’s life failed, the damage was done. O’Hara endured weeks of excruciating surgeries and faced a grueling recovery process, all because of one man’s obsession with an inheritance.
