Malcolm Webster, a British nurse dubbed the "Black Widower," was convicted in 2011 for the 1994 murder of his first wife, Claire Morris, and the 1999 attempted murder of his second wife, Felicity Drumm, both staged as car accidents to claim life insurance money. Operating as a calculated, financially-driven sociopath, Webster drugged his victims and attempted to kill them on different continents to fund an affluent lifestyle, eventually defrauding his second wife of her savings.
