Horrific moment murdered schoolboy, Sebastian Kalinowski, is in so much pain he struggles to sit during campaign of abuse by his mother Agnieszka Kalinowska and her partner Andrzej Latoszewski
A sadistic mother branded ‘the greatest evil that walks this world’ was today jailed for life with a minimum of 39 years for killing her son – as a chilling video emerged showing her ‘tortured’ teen cowering in his bedroom before his death.
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.’
The judge’s comments came as chilling footage was this afternoon released by police showing Sebastian before his death.
The 22-second video, captured on CCTV, shows the teen gingerly making his way across his bedroom to sit on a stool.
Wearing shorts and a t-shirt, the youngster slowly lowers himself to the seat where he sits hunched over and facing a wall.
Addressing the Sebastians killers in court today, 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.’
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.
