A mother and her partner have been found guilty of murdering her 15-year-old son who died after a campaign of torture.
Sebastian Kalinowski died of an infection caused by “untreated complications of multiple rib fractures”, after weeks of what prosecutors described as “cruel assaults and abuse” at the hands of his mother Agnieszka Kalinowska, 35, and her long-term partner Andrzej Latoszewski, 38.
A jury at Leeds Crown Court heard that Sebastian was beaten with a bed slat, whipped with an extension cable and stabbed with a needle by his mother and her partner.
