Mum and boyfriend ‘laughed as they filmed themselves torturing her son to death with bed slat, cable and needle’

A MUM and her boyfriend were said to have laughed as they filmed themselves cruelly torturing her teenage son to death.

Sebastian Kalinowski, 15, died last August of an infection caused by “untreated complications of multiple rib fractures”.

It allegedly came after weeks of “cruel assaults and abuse” at the hands of his mother Agnieszka Kalinowska, 35, and her long-term partner Andrzej Latoszewski, 36.

Leeds Crown Court heard that the 15-year-old had been in the UK for less than a year after moving from Poland to live with his mother and her boyfriend.

The teen was beaten with a bed slat, whipped with an extension cable and stabbed with a needle during a campaign of “torture” at the hands of the couple, according to prosecutors.

After the couple were arrested in connection with Sebastian’s death, police seized CCTV cameras from their house in Huddersfield, West Yorkshire.

Prosecutor Jason Pitter QC said the technology had been installed partly to “monitor and exert control over Sebastian remotely”.

“In a twist, it is that system that has recorded the abuse he had to endure,” he told the court.

Kalinowska and Latoszewski deny murder and alternative counts of manslaughter and causing or allowing the death of a child, as well as a charge of neglect.

Mr Pitter said both defendants will argue their treatment of Sebastian was “reasonable chastisement”.

The court heard Sebastian came to Huddersfield in October 2020, with teachers describing him as “a pleasant and well-mannered boy” who “was observed to be quiet and timid, and at times appeared sad”.

Mr Pitter said: “In the very early stages it would appear that, at least for Kalinowska, she was glad that her son was here with her.

“She was described by a friend as being “smitten”. If that was correct, that was unfortunately to change rapidly.”

He told jurors that by New Year’s Eve the defendants’ attitude was that Sebastian was “something of a hindrance” and they spoke about him being a liar and playing truant from school.

Mr Pitter told jurors: “You may conclude that these were attempts to justify what they would present as a need for Sebastian’s ‘punishments’.

“The punishments, if that is an appropriate way to describe them, were by any stretch of the imagination cruel and became increasingly more severe and violent over time.”

He said: “It would appear that the punishments were precipitated by things such as Sebastian merely dropping food on his bedroom floor, or even just having gone to the toilet during the night.”

Jurors heard that on the morning of Sebastian’s final day, he went through “the routine of being assaulted by both defendants”.

Mr Pitter said CCTV showed Latoszewski taking Sebastian out of the bedroom at 8.25am, before carrying him back around 15 minutes later, “naked, clearly wet and unconscious”.

He said: “Whilst some limited efforts were made by Latoszewski to perform CPR, the reality is it may have been too late as Sebastian showed no sign of life once he was brought back into the bedroom.

“At 9.24am, Latoszewski appeared to be trying to pour water into Sebastian’s mouth before then blowing into it.

“Was that the beginnings of an attempt to give the impression that Sebastian had drowned by trying to force water into his airways?”

The trial continues.
