Sentence: 19 years imprisonment
Paul Mallin killed his ex-girlfriend Karen Read and her 86-year-old fiancé John Down in brutal circumstances at Fernways sheltered housing unit in Cecil Road, Ilford, on September 5, 2015. Motivated by anger over Miss Read choosing Mr Down over him, Mallin had previously stabbed Mr Down's wall with a knife, spat at him, and searched online more than 300 times for poisons, including 'poison that doesn’t show up in an autopsy' and references to 'Ricin' from the TV show Breaking Bad. On the night of the incident, he attempted to force entry into Mr Down's flat armed with a knife and a meat cleaver, stabbing Mr Down multiple times while he tried to defend the door, and then stabbing Miss Read, who was disabled and witnessed the attack from her armchair.
