Family of Greek heiress, 30, who died from ‘toxic insect bite’ after being discharged from London hospital condemn ‘outrageous’ wait for answers a year after her death
Marissa Lemos, a 30-year-old Greek heiress, was found dead in her London townhouse on 11 September 2025, hours after being discharged from University College London Hospital (UCLH) following treatment for symptoms arising from an insect bite. Her family now demands accountability, claiming she was discharged without being assessed by a qualified NHS doctor and were only seen by trainee medics, despite being visibly unwell. The case raises serious questions about discharge decisions and patient care in the NHS.
A year after her death, Marissa's parents still lack an official cause of death. The post-mortem examination proved inconclusive, and the family remains without toxicology results despite being told testing was completed in June 2026. Police have indicated further microbiology tests are required, with the coroner yet to determine whether an inquest will be held. The family is pursuing legal action for alleged clinical negligence and criticises the hospital's decision to discharge their daughter when they believe she should have been kept overnight.
