Mother and her bodybuilder partner are both jailed for 39 years for murder of her 15-year-old son

A sadistic mother branded ‘the greatest evil that walks this world’ was today jailed for life with a minimum of 39 years. 

Schoolboy Sebastian Kalinowski, 15, suffered months of horrific abuse at the hands of his mother Agnieszka, 36, and his step father Andrzej Latoszewski, 38, a steroid-injecting martial arts fighter.

The teenager was beaten repeatedly at his Huddersfield home with a bed slat, whipped with an extension cable and stabbed with spent hypodermic needles his step father had used.

He died after untreated multiple rib fractures caused sepsis and organ failure.

Much of the sickening abuse was captured on a CCTV camera system set up around the family home in Huddersfield, West Yorkshire, to ‘monitor and control’ Sebastian.

Sentencing the pair for murder and child cruelty at Leeds Crown Court, Mrs Justice Lambert, told Latoszewski: ‘You punched and kicked and kneed his body in the same way as you did your punchbag.

‘Kalinowski, you just didn’t care what happened to Sebastian one way or another and seems oblivious of the pain you were inflicting.’

Addressing the pair, Mrs Justice Lambert said: ‘Anyone who has watched even part of the CCTV footage can only be utterly horrified by what they saw and bewildered why anyone would behave this way to a teenage boy. It begs the question why anyone would behave in this way? This is a question I have myself.’

Teen’s heartbroken father labels his son’s killers ‘ruthless monsters’ and says: ‘The wound you have inflicted will never heal… I hate you’ 

‘You turned every day in his life into a nightmare and committed monstrosities that are truly mindboggling. I will never comprehend how much hatred it takes to do such thing. The question is why?

‘On 13th August 2021, my whole world came tumbling on me. The news of his death made part of me die with him. 

‘The wound you’ve inflicted will never heal and the pain will never go away. The knowledge his life was taken in such a brutal way is such a blow for me and my family. 

‘Nothing is ever going to be the same every again and it is not the truth that time heals all wounds.

‘This nightmare comes to haunt me every single day. Sebastian was craving your love, attention. How can you be such ruthless monsters, without an ounce of humane feeling. 

‘The crime you committed on my son, the crime you did to him. I hate you, I hate you. I hope justice pays you. For you there will be no forgiveness and I hope every time you close your eyes you see his face when he is in excruciating pain, and this stays with you forever.

‘All those punishments of yours – the fact you had been humiliating him so much only testifies how ruthless you are, how much monsters you are.’

 

Watching proceedings from Poland, Sebastian’s heartbroken father Jacek described his ex-wife, who listened to his words in the dock with tears in her eyes, as ‘the greatest evil that walks this world’.

In his victim personal statement he continued: ‘You are a truly cruel tyrant.

‘How can you be such ruthless monsters?

‘Sebastian wished to make you love him. You reciprocated his love with pain.

‘You are going to have to pay for every one of his tears.’

The pair of killers, who married each other while languishing in jail after being convicted earlier this year, were both jailed for life with a minimum term of 39 years.  

During their six-week trial, jurors were forced to sit through hours of ‘horrifying’ footage showing Sebastian being abused and tormented.

So shocking was the level of violence used against the innocent teenager, jurors were discharged from jury service for life by The Honourable Mrs Justice Lambert who told them: ‘You have had to endure horrifying footage of Sebastian Kalinowski in great pain and then in death. 

‘You have discharged your duty as jurors in a truly commendable way. May I thank you for all of your dedication and patience. May I also thank you on behalf of the justice system.’ 

Kalinowska previously admitted child cruelty, while Latoszewski, a steroid-abusing martial arts fanatic, admitted manslaughter, but both had denied murder.

Sebastian moved to the UK from his native Poland, where he lived with his father, in October 2020, 10 months before his death.

But life with his mother and stepfather turned into a prolonged and miserable period of suffering.

The ‘shy’ teenager attended secondary school in Huddersfield where he was described as a ‘model pupil.’ He was small and thin and looked younger than his age.

Teachers were unaware of the horrors unfolding at home where he was viewed by the parents as a ‘hindrance.’

Prosecutor Jason Pitter, QC, told the jury the abuse became ‘increasingly more severe and violent.’

He was treated like a ‘gopher or lapdog’ and made to call Latoszewski ‘Mr’ or ‘Sir.’

Between beatings the teenager was forced to ‘humiliating drills’ such as squats and press-ups.

CCTV footage seized by police revealed a wealth of chilling evidence.

In one 30-minute clip played to the jury Latoszewski was seen hitting the boy more than 100 times, pausing at one stage to wipe the sweat from his face, while Kalinowska watched TV and ate toast.

In the weeks before his death in August last year Sebastian suffered repeated violent attacks.

In one the stepfather whipped him with a cable, with at one stage his mother grabbing him by the neck and throwing him to the ground.

Mr Pitter said punishments were ‘precipitated by things such as Sebastian dropping food on his bedroom floor or having gone to the toilet during the night.’

Three days before he died Latoszewski punched, kicked and throttled the teenager in a prolonged beating lasting more than four hours.

‘Sebastian frequently struggled to stand but was picked or held up in order that the assault could continue,’ said Mr Pitter.

The day before his death Sebastian was punched and kicked and both mother and stepfather stabbed him with a needle before assaulting him further in the bedroom.

Kalinowska tried to force a slipper into her son’s mouth towards the end of the assault. Footage from that day showed Sebastian in ‘considerable pain’ and struggling to breathe, the court heard.

As she sentenced them to life in prison, The Honourable Mrs Justice Lambert told Kalinowska: ‘You just did not care about Sebastian, you were only interested in yourself’. She branded Latoszewski a ‘bully’.

‘Like all bullies, unable to maintain respect in another way you sought to intimidate Sebastian who was weaker than you and in Sebastian you found a way.’

After the couple were arrested in connection with Sebastian’s death, police seized CCTV cameras from their house in Huddersfield, West Yorkshire, which prosecutors said had been installed partly to ‘monitor and exert control over Sebastian remotely’.

On the day before his death, Latoszewski was seen on the CCTV ‘forcing food and drink into Sebastian’s mouth’ and ‘stabbing him a number of times’ with a needle in the groin and thigh, ‘apparently laughing whilst he did so’. 

Sebastian was found unconscious by paramedics at a house in West Yorkshire on Friday August 13, 2021. He did not survive having been out cold for almost three hours before help arrived.

A court heard Sebastian had suffered multiple injuries, including open wounds to his buttocks and numerous rib fractures, which the prosecution said caused the complications which led to his death.

Kalinowska previously admitted child cruelty, while Latoszewski, a body builder and martial arts fanatic, admitted manslaughter, but both had denied murder.

However, they were both today convicted of Sebastian’s murder by a jury following after a five-week trial at Leeds Crown Court. 

The jury previously heard Kalinowska has accepted a marriage proposal from Latoszewski while in prison awaiting trial.

In letters read to court Kalinowska wrote ‘Yes, yes, yes’ when her lover proposed from his jail cell. She said she would marry her partner: ‘Anywhere. Even in a tracksuit. I don’t need a wedding dress’.

Despite being in prison before being guilty of killing her own son, she said:  ‘Too many beautiful moments we’ve lived through. Too many years together to be forgotten.

Cruelty of sadistic couple who should have cared for and loved Sebastian, 15

Kalinowska and Latoszewski inflicted mental abuse by shouting derogatory insults at Sebastian in an effort to control and humiliate him.

Latoszewski insisted Sebastian address him as ‘Mr’ or ‘Sir’.

When emergency services were eventually called to the house, Sebastian had been unconscious for two and a half hours, the CPS said.

He was taken to hospital where he was pronounced dead. Latoszewski suggested variously that Sebastian had drowned in the bath, had fallen from a tree, and had been in a fight.

Sebastian, who had just turned 15, had been in the UK for less than a year. He was described by his teachers as a model pupil, meticulous, punctual and well-mannered.

Daniel Lee, Senior Crown Prosecutor, from the CPS said: ‘Agniewska Kalinowska and Andresz Latoszewski were the two people Sebastian should have been able to trust the most in the world. But instead of loving, protecting and caring for Sebastian, they subjected him to an utterly horrific and prolonged campaign of extreme physical and mental abuse.

‘In short, they tortured him. After suffering many months of mental and physical torment, Sebastian died of the multiple injuries he sustained at their hands. Both defendants lied and offered cowardly and implausible explanations for the extent of Sebastian’s injuries, and attempted to pass it off as ‘appropriate discipline’.

‘It is impossible to contemplate the agony and fear this young boy experienced, inflicted in his own home, by his supposed care-givers.

‘The defendants are now facing very many years in prison. Our thoughts remain with Sebastian’s other relatives and we sincerely hope the successful outcome of this case will bring them some comfort.’

 

‘Each night I go to sleep and I look at the sky know you are somewhere far away. Keep your head up, be strong. Remember you’ve got me. I am yours forever’.

North Huddersfield Trust School Headteacher Andrew Fell said Sebastian spoke very little English when he arrived in October 2020 but ‘began to build relationships and develop more confidence in his spoken English’. 

Mr Fell said Sebastian used Google Translate to communicate. His school said Seb showed little sign of being a victim of abuse, was always smartly dressed and was not seen with visible injuries,

He died on 13 August last year, around three weeks into the school summer holidays.

Mr Fell said: ‘Sebastian was happy at NHTS. His spoken English improved significantly, helping him blossom from an initially shy student into one with much more confidence and a strong circle of friends.

‘Caring, intelligent and fun-loving, he will be remembered for his charming smile, his sharp sense of humour and his kindness.

‘He embodied what our school stands for in demonstrating a positive attitude to school, treating others with respect and showing a determination to make the most of his education.

‘Our close-knit school community is deeply saddened by the loss of Sebastian.’

Jurors had previously been shown ‘horrifying’ CCTV footage from the couple’s home, which the prosecution said was installed to monitor Sebastian.

Videos showed numerous incidents in which Sebastian was repeatedly punched, kicked and stamped on. In one video, he was shown being whipped with a cable.

The judge, Mrs Justice Lambert DBE, took the unusual step of discharging all jurors from future jury service due to the nature of the evidence they had sat through.

Addressing the jury, she said: ‘Your commitment and your dedication to this case has been truly extraordinary, it really has.

‘You have had to endure quite horrifying footage of Sebastian suffering great pain over a period of time and then his death.

‘May I thank you personally for all of your hard work, dedication and patience over the last six or so weeks.’

Jason Pitter QC, prosecuting, previously told the court Sebastian suffered ‘weeks, if not months of terrible, cruel, systematic assaults and ill treatment, neglect and abuse’.

The court heard Sebastian had been in England for less than a year after moving from his home country of Poland, where he lived with his biological father.

Sebastian attended North Huddersfield Trust school, where he was described as a ‘model pupil’, the court heard.

But his mother and step-father claimed he needed punishing for lying and playing truant from school.

The judge deferred sentencing on the pair, both of Leeds Road in Huddersfield, until October at the earliest.

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

Prosecutor Jason Pitter QC 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 from January 2021, ‘the disciplining of Sebastian became progressively harsh’ and that he was ‘kept deliberately out of the way of others, either as part of the system of punishment or to hide the abuse.’

Mr Pitter said emergency services were called to the defendants’ house by Latoszewski on August 13 ‘after Sebastian had been unconscious for some two and a half hours’.

He told jurors Latoszewski said he had found Sebastian in the bath with his head under water, ‘suggesting perhaps that he had drowned’.

The court heard that an examination of Sebastian revealed injuries including bruising to his buttocks, forehead, jaw, abdomen, arms and legs, and multiple rib fractures.

Mr Pitter said: ‘[The defendants’] telephones were seized and that installed CCTV system was interrogated.

‘Together, their contents document the catalogue of abuse that Sebastian had endured before his death.

‘A broad description is one of Sebastian being attacked, principally and most severely by Latoszewski, but with his mother being involved at various times.

‘It included messages and recordings of conversations which have the defendants speaking of and to Sebastian in the most derogatory and inhuman ways, in the context of a perceived need to punish him.

‘That included forcing him to undertake physical and humiliating drills, even when he was too weak to really do so.’

Footage played to jurors included Latoszewski beating Sebastian’s buttocks with what, Mr Pitter said, appears to have been a slat from a bed.

Further clips included Latoszewski making Sebastian do exercises and whipping him with an extension cable to ‘spur him on’.

Mr Pitter said video from Latoszewski phone also contained clips of him ‘verbally abusing’ a ‘visibly upset’ Sebastian.

On August 10 last year, Mr Pitter said, CCTV showed violence towards Sebastian starting at 8.15am and continuing until ‘at least’ 4.10pm.

He could be seen ‘frequently struggling to stand but [being] picked or held up in order that the assault could continue,’ jurors heard.

Mr Pitter said on the day before Sebastian’s death, Latoszewski was seen on the CCTV ‘forcing food and drink into Sebastian’s mouth’ and ‘stabbing him a number of times’ with a needle in the groin and thigh, ‘apparently laughing whilst he did so’.

He added that Kalinowska at one point ‘took over stabbing Sebastian with the needle’.

Mr Pitter said the defendants’ telephones and CCTV footage ‘document the catalogue of abuse that Sebastian had endured before his death’.

He said: ‘A broad description is one of Sebastian being attacked, principally and most severely by Latoszewski, but with his mother being involved at various times.
