Piotr Swiderski, a Polish national, and his three sons, Dominik, Nikodem, and Kacper, were found dead in their home in Staines-Upon-Thames, Surrey, on Saturday. Authorities are investigating the incident, which they believe to be isolated with no third-party involvement. The mother, Angelika Swiderska, has paid tribute to her husband and children, describing them as loving and happy. Surrey Police have referred themselves to the Independent Office for Police Conduct due to prior contact with the family in August 2023. Floral tributes have been laid outside the house, and the community is in mourning. Post-mortems and formal identifications are pending as the investigation continues.
