Marissa Laimou: Sepsis from Insect Bite Cited as Cause of Death in Autopsy – ‘They Sent Her Home Despite Diagnosis’

New details have emerged regarding the cause of death of Marissa Laimou, who passed away in September in London. According to the Daily Mail (30.09.2025), the autopsy reveals that the 30-year-old died from sepsis triggered by an insect bite. The report states the preliminary finding as ‘sepsis resulting from an insect bite, compounded by underlying vulnerability due to chemotherapy and HLH.’ Laimou, heiress to a prominent Greek shipping family, had sought medical help at a London hospital but was sent home—only to pass away hours later in her bed. Days before her death, she experienced dizziness, itching, and fever, prompting her visit to the hospital where she was being treated for breast cancer. Her family continues to demand answers about which insect bit her, when and where it happened, and why she was discharged from University College London Hospital (UCLH) under NHS care. The family has launched legal action and criticized authorities over the autopsy delay of more than two weeks. A close relative told the publication: ‘Didn’t they know what could happen to someone with such a vulnerable medical history? Sepsis spreads rapidly and can kill within hours if not treated immediately.’ The family claims a doctor admitted to Laimou’s mother that her daughter was seen only by nurses, not doctors. ‘They had the diagnosis and still sent her home. A young woman lost her life just hours after leaving the hospital where she’d been rushed for urgent care,’ the relative emphasized. Blood tests were reportedly reviewed by a physician who never examined Marissa in person, despite her low blood pressure. Today, her body will finally be released to her family ahead of her funeral and burial in the family plot in Athens.
