A banker who was murdered by his partner reportedly offered her £70,000 and a plot of land in Greece as part of a breakup deal, a court has heard. Henrik Slotsaa, 52, told his partner, Joanna Cierpka, 51, on her birthday that he had met someone else he "liked." This admission came months before Slotsaa's body was found at their home in Elephant and Castle, south London, in March. Police discovered him dead in his bedroom, while Cierpka was found injured in the living room. Cierpka, from Poland, denies the murder charge but claims she is guilty of manslaughter due to diminished responsibility, suggesting her mental state may have been impaired at the time. A prosecution psychiatrist testified that jealousy over Slotsaa’s new relationship with Aimee O'Shaughnessy might have played a role in the alleged murder. Slotsaa had met O'Shaughnessy at a work event in November 2025, a few months after he started working at Citibank’s Canary Wharf offices. The two exchanged phone numbers and had lunch on several occasions, including in January 2026. During one of these meetings, Slotsaa told O'Shaughnessy he "enjoyed spending time" with her, though she said she wasn't ready to "get involved with someone" at that point in her life. O'Shaughnessy described their relationship as being just friends, though Slotsaa had mentioned having a "hard time" in his relationship with Cierpka. He told O'Shaughnessy that Cierpka was suffering from depression and had stopped taking her medication. Slotsaa had also confided in O'Shaughnessy about his plan to financially resolve things with Cierpka so they could separate. He was working out a plan that he believed could potentially work, though he was concerned about it because he felt it wasn't the right thing to do, given Cierpka's mental health. In one text message to O'Shaughnessy, Slotsaa wrote: "I always need you for some reason, I can’t explain." O'Shaughnessy responded: "We’re def friends for life so you are stuck with me." After her arrest, Cierpka told a psychiatrist that Slotsaa had admitted in December that he no longer loved her and had met someone else at work. Jurors also heard that Cierpka told a hospital staff member she had "killed her partner," a statement recorded in a note dated and signed by her. The trial continues as the court examines the evidence and testimony.
