U.K. doctor admits trying to kill with poison disguised as COVID vaccine

Prosecutor said Thomas Kwan used his 'encyclopedic knowledge' of poisons in his plot to kill his mother's long-term partner, who ultimately survived

LONDON — A British doctor on Monday admitted trying to kill his mother’s long-term partner, who stood between him and an inheritance, by injecting the man with poison disguised as a COVID-19 vaccine.

Prosecutors say Thomas Kwan pretended to be a community nurse delivering booster shots and injected Patrick O’Hara with a toxic substance, likely a pesticide. O’Hara, 72, developed a rare flesh-eating disease that left him in intensive care.
