What the court heard

She was found guilty of murder in Huddersfield, West Yorkshire, on 13 August 2021. She pleaded guilty to child cruelty. Sentencing Remarks 1. Sebastian Kalinowski died on 13 August 2021. He was 15 years old. In the weeks before his death, Sebastian had been subjected to horrific physical abuse. At the post mortem examination he was found to have 23 rib fractures. There was a large blood clot in his liver. His heart muscle was damaged. There was evidence of a muscle shearing injury to his left thigh. There was a very large number of linear scabs across his lower back and buttocks, the result of wounds to that area which had been cut so deep that the fat had been stripped down to the muscle. Sebastian did not die as a direct result of any one of those injuries but from an infection which set in around the rib fractures which developed into overwhelming sepsis and collapse. The uncontroverte d medical evidence was that in the few days before his death the infection would have caused Sebastian to be very unwell, short of breath, very weak, and obviously so. 2.

It shows you, Latoszewski, using your martial arts techniques to punch and kick and knee Sebastian repeatedly about the torso and head: using Sebastian's body in the same way as you used the punch bag which hung in your garden. The footage shows you beating Sebastian with a bed slat and an electric cable over his lower ba ck and buttocks to such an extent that it caused bruising and bleeding leading to the welts which were found on his body after his death. 4. Kalinowska you were almost always present when this abuse was inflicted. Sometimes you watched Latoszewski as he set about Sebastian. On other occasions you sat indifferently on the sofa, eating or drinking and watching television. On many occasions yo u were an active participant in the abuse. You landed blows on Sebastian too. You encouraged Latoszewski by either initiating or joining in the abuse by…
