A mental health trust has confirmed that a man found dead along with three family members in Costessey near Norwich was one of its patients. Bartlomiej Kuczynski, 45, was discovered with stab wounds to the neck alongside his sister-in-law and two daughters on 19 January.
Mr Kuczynski was taken to Norfolk & Norwich University Hospital by police on 14 December after being reported missing, but discharged himself after being assessed as having mental capacity. The Norfolk & Suffolk NHS Foundation Trust, which provides mental health services, said it would conduct a full externally-led serious incident review.
Caroline Donovan, chief executive of the trust, stated: 'We will be undertaking our own full externally-led serious incident review to ensure any learning is identified and, of course, work with partners to collaborate with any external investigations.' She added that the trust wanted to be 'open and transparent' while balancing the needs of the family.
Norfolk Police has referred itself to the Independent Office for Police Conduct (IOPC) over the case. The force confirmed it received a call from Mr Kuczynski shortly before 06:00 GMT on the day of the deaths, in which he said he was confused and worried about his mental state. He was advised to seek medical advice and contact 111.
Officers arrived about an hour later after a second call from a concerned member of the public, and discovered the bodies. Detectives are treating the deaths of Jasmin Kuczynska, 12, Natasha Kuczynska, eight, and Kanticha Sukpengpanao, 36, as murder, but are not treating Mr Kuczynski's death as suspicious and are not looking for anyone else.
