'Bad' Stepfather and Mother jailed for murder and torturing teenage son

Sebastian Kalinowski was abused by Agnieszka Kalinowska and her partner Andrzej Latoszewski for months. 

        The 'evil' couple who murdered a 15 years old boy after subjecting him to an 'absolutely appalling and prolonged campaign of extreme physical and mental abuse was jailed for almost 80 years. Agnieszka Kalinowska, 35, and her longtime partner Andrzej Latoszewski, 38, inflicted a series of horrific injuries on their son Sebastian Kalinowski over the last few months.

Schoolboys had to endure depraved "punishments" for "small", and "childish transgressions", such as dropping food on the floor and going to the bathroom at night. They were beaten with bed frames, flogged with extension cords, stabbed with needles, and subjected to "the most disrespectful and inhumane" insults.

Judge Lambert previously praised jurors for multiple viewings of "fairly terrifying" CCTV footage from cameras the couple had installed in their home in Huddersfield, West Yorkshire, to monitor and control Sebastian.

Catching the couple, she said: "Anyone who saw some of the CCTV footage of what happened in this house last summer was just heartbroken and very confused by what they saw. Who should be a beloved child or stepchild?"

She told Ratshevsky, "I think your abuse was motivated by a desire to dominate and dominate Sebastian to the point of almost oppressing him." "You didn't care what happened to Sebastian. You didn't seem to realize the pain you were inflicting."

The day before Sebastian's death, Latoszewski forced food and drink into the boy's mouth and repeatedly pricked his groin and thigh with needles. Prosecutor Jason Pitter KC said at trial that the bodybuilder was "obviously laughing while doing this."

He said that Kalinowska once "pricked Sebastian with a needle."

On the morning of his death, 13 August 2021, a Leeds Criminal Court jury heard that he had "experienced routine assaults by both defendants". The court ruled that Sebastian suffered injuries including bruises to his buttocks, forehead, jaw, abdomen, arms, and legs, multiple broken ribs, and died of infections caused by "untreated complications of multiple broken ribs." He was in the UK less than a year after moving from Poland to the defendant.

His father, Jacek Kalinowski, has branded the couple "reckless monsters" and, in a statement on the impact on victims, said, "No crime is more horrific than murder, especially when it involves children."

"You turned every day of his life into a nightmare and committed a truly phenomenal monster. I can't comprehend how much hatred it takes to do something like that."

"I've made many mistakes as a parent. I may not be the perfect father, but I loved Sebastian, so I wanted to protect him from the evil done to him by his own mother." Couldn't...you are the best...the evil that walks this earth.

"No forgiveness for you. I hope that every time I close my eyes, I see Seb, a scared little boy, in pain."

"I hope this image will remain in your heart and stay with you forever."
