Story summary

On February 19, Joanna Cierpka, an unemployed business executive from Poland, told London's Central Criminal Court that she had searched the internet for phrases like "I don’t want to live anymore" and "how to end it." Her testimony came during her trial for fatally stabbing her boyfriend, Henrik Slotsaa, a Citibank banker. Cierpka described feeling depressed after discovering text messages between Slotsaa and another woman on his phone around the time of their anniversary in January.

During questioning by Jacqueline Carey KC, representing Cierpka, it was revealed that Slotsaa had been aware of her suicidal thoughts but didn't fully understand her depression. He allegedly told her multiple times she should "kill yourself already," showing a dismissive attitude towards her mental health struggles. The court heard that Slotsaa also expressed annoyance at Cierpka's scratching due to eczema and implied he would benefit from the flat they jointly owned if she committed suicide.

This case highlights issues around understanding and responding to someone’s severe depression, raising questions about emotional support in intimate relationships and legal responsibility for harmful behavior.
