Sebastian Kalinowski: Couple jailed for murdering teenage son after 'horrific' campaign of abuse

A mother and her partner have both been jailed for life with a minimum term of 39 years for murdering her son during a campaign of "horrific and prolonged 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 the 15-year-old, who had been in the UK for less than a year after moving from Poland to live with his mother, was beaten with a bed slat, whipped with an extension cable and stabbed with a needle at the couple's home in Huddersfield, West Yorkshire.

Sebastian's father Jacek Kalinowski watched proceedings by video link from Poland.

Sentencing Kalinowska and Latoszewski, Mrs Justice Lambert told them: "You, Latoszewski, are a bully. Like all bullies, you sought to intimidate and frighten Sebastian, who was weaker than you.
