Teen, 18, stabbed man to death in his car in ‘fit of anger’ after he tried to grab her breasts


A TEENAGER who stabbed her admirer to death in a “fit on anger” after he tried to grab her breasts was today jailed for life.

Martyna Ogonowska, 18, claimed to have forgotten she had a knife in her hand during an argument following a night out in Peterborough.

She said she “lost view” of the blade which was in her hand and only realised she had it when she saw it in Filip Jaskiewicz’s chest.

The court heard the pair had only met three days before the fatal stabbing on October 31, 2018.

A post-mortem examination at Peterborough City hospital concluded he died from a single stab wound to the chest.


Ogonowska claimed to then pull the knife out from his chest and told a court how she wanted to call an ambulance and stop the 23-year-old from bleeding – but ran away with her two friends.

The court heard how she went to an ex-boyfriend’s house, where she cleaned the knife and then turned herself into the police.

A jury today convicted Ogonowska of killing Mr Jaskiewicz and she was jailed for life with a minimum of 17 years.

Judge David Farrell said: “There is only one sentence the court can impose: custody for life.

You took a knife to the scene intended to have it available to use it as a weapon and you used that knife in committing the murder.

“However I must determine the minimum term you must serve before which you may even be considered for release.”

Judge Farrell continued: “You took a knife to the scene intended to have it available to use it as a weapon and you used that knife in committing the murder.

“Accordingly 25 years is the starting point. I must then consider the statutory and mitigating factors.


“This was a killing that took place in public, on the street in a residential area and in the presence of two witnesses.

“The mitigating factors are those and there are a number of them.

“I am satisfied that your intention in this case was to cause really serious bodily harm instead of to kill.

“I reach that conclusion because this was a single blow, a back-handed act.

“You hit his heart and you realised that when you then pulled the knife out.

“But the fact is it was a single blow during the incident and it causes me not to be sure if you had an intention to kill.”

He also took into account her young age, the fact that she was “of low mental capacity”, and previous trauma including bullying and postnatal depression.

Judge Farrell imposed a sentence of custody for life with a minimum of 17 years for the murder charge.

Ogonowska was also sentenced to 18 months for the possession of a knife charge, which will run concurrently.
