A 15-year-old boy who was murdered by his mum and her partner suffered a campaign of “horrific and prolonged torture”.
Sebastian Kalinowski died of an infection caused by 'untreated complications of multiple rib fractures' after weeks of “cruel assaults and abuse”, a court has heard.
His mother Agnieszka Kalinowska, 35, and her long-term partner Andrzej Latoszewski, 38, have now both been jailed for life with a minimum term of 39 years.
