You may have heard about the twisted case of Dr Thomas Kwan.
 
He’s the GP who’s gone on trial after being accused of trying to kill his own mother’s partner by injecting him with poison.
 
By disguising himself as a nurse, Kwan administered a fake Covid jab, which was in fact a pesticide, leaving 71-year-old Patrick O’Hara hospitalised.
 
Kwan is due to be sentenced this week.
 
So, what’s behind the murder plot?
