A Hull man has been found guilty of killing an unborn child after a violent and prolonged attack on a pregnant teenager.
Stefan Marin, aged 19, of New George Street in Hull, was convicted at Hull Crown Court of child destruction, grievous bodily harm with intent, non-fatal strangulation, false imprisonment, and perverting the course of justice.
The verdict came after a ten-day trial that concluded on Friday 17th October 2025.
Girl attacked for four hours
Jurors heard how Marin assaulted the 17-year-old girl at his home on Thursday 13th March 2025 during a sustained four-hour attack.
He punched, kicked, strangled and scalded her, targeting her stomach despite knowing she was pregnant.
At around 10.20pm that evening, a member of the public found the teenager collapsed in the street, bleeding and barely conscious.
She was taken to hospital where doctors confirmed she had suffered a broken nose and severe trauma.
Tragically, scans revealed her baby, who was 29 weeks gestation, had died.
Evidence of concealment
Police officers found Marin’s flat had been cleaned with bleach and the girl’s clothing discarded outside.
CCTV showed Marin walking the victim to an alleyway and leaving her there before threatening her not to tell anyone what had happened.
He was arrested the following day on Great Thornton Street in Hull.
‘Utterly inhumane’ attack
Detective Chief Inspector Jon Cross, who led the investigation, said: “This was a deeply disturbing, violent, and harrowing attack on a vulnerable young girl, which resulted in the unfathomable loss of her child that was just weeks away from being born.
“Marin’s actions were calculated and utterly inhumane. After subjecting her to hours of sustained violence, he then left her alone in the street, knowing full well the extent of her injuries. That level of disregard for her life and wellbeing is truly appalling.”
He praised the victim’s “immense courage and resilience” throughout the investigation and court proceedings, describing her bravery as “nothing short of remarkable.”
Victim’s statement
A statement from the girl, read in court by Detective Sergeant Nathan Francis, said: “What happened to me was something no one should ever have to go through. I was beaten for hours and suffered injuries that permanently changed my life – but the greatest pain of all was losing my baby boy.
“I’ve had to find strength I never knew I had, and while nothing can bring my baby back, I hope that by speaking out, I can help others who are living with abuse realise there is a way out and that they are not alone.”
Rare conviction
Edmund Hall, Senior Crown Prosecutor at the CPS, said: “This was a brutal crime, where the defendant viciously assaulted not only a young girl, but also a defenceless unborn baby.
“The charge of child destruction is rarely brought, but the evidence clearly showed the seriousness of this case. We thank Humberside Police for their detailed investigation and above all the victim, whose courage has ensured justice for her unborn baby.”
Marin has been remanded in custody and will be sentenced at Hull Crown Court on a date to be confirmed.
