Doctor admits disguising himself as a nurse to try to kill his mother's partner with poison: "Stranger than fiction"
Prosecutors said Thomas Kwan used his "encyclopedic knowledge" of poisons in his plot to kill Patrick O'Hara.

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, was given a toxin which caused a "rare and life-threatening flesh-eating disease," Newcastle Crown Court heard, the BBC reported.
