Polish Killers

Damian Rzeszowski was convicted of six counts of manslaughter after killing his wife Izabela, their children Kinga and Kacper, his father-in-law Marek Garstka, and family friend Marta de la Haye and her daughter Julia in St Helier, Jersey, on August 14, 2011. Rzeszowski attacked the victims with kitchen knives during a violent episode following the breakdown of his marriage. His defence successfully argued diminished responsibility caused by severe depression and psychotic symptoms, and he was cleared of murder. He was sentenced to 30 years imprisonment for each victim, to run concurrently. Rzeszowski died by suicide in prison in 2018.
