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.
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.
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.
