A police employee is facing a misconduct probe over the deaths of Bartlomiej Kuczynski, 45, his daughters, Jasmin, 12, and Natasha, seven, and his sister-in-law, Kanticha Sukpengpanao.
Samantha Goward appeared to begin to cry as she opened the inquest into the death of Natasha Kuczynska, 8, who died at a house in Costessey with three other family members.
Bartlomiej Kuczynski, 45, his daughters Jasmin, 12, and Natasha, eight, and his sister-in-law, Kanticha Sukpengpanao, 36, were all found dead from stab wounds in Costessey, near Norwich.
The body of Bartlomiej Kuczynski, girls Jasmin, 12, and Downreuang, seven, and their aunt were found at a property in Costessey, near Norwich, on Friday morning.
A police chief has called for a deeper review into his own force amid concerns after officers did not respond to a 999 call from a home where four people were found dead.
