I tell the story of John Sweeney, Melissa Halstead and Paula Fields in this episode.
John murdered and dismembered Melissa Halstead and Paula Fields, two former girlfriends, before dumping their remains in canals in Rotterdam, Netherlands and London, England.
He was already serving a life sentence for attempted murder on a third ex-girlfriend when he was linked to the murders of Melissa and Paula.
He was subsequently handed a Whole Life Order.
