A 15-year-old boy who was tortured and killed by his mother and her partner in a campaign of “utterly horrific and prolonged” torture was murdered by the two people he “should have been able to trust the most in the world”, a senior prosecutor has said.
Sebastian Kalinowski died of an infection caused by weeks of abuse at the hands of his mother, Agnieszka Kalinowska, 35, and her long-term partner, Andrzej Latoszewski, 38, which included him being beaten with a bed slat, whipped with an extension cable, and stabbed with a needle, as well as “the most derogatory and inhuman” verbal abuse.
