She also feels bitter that the serial sex attacker who took Katerina’s life fled to Britain from Poland where he was under arrest for rape.
A Polish judge gave him three months bail to get a hip operation.
Left unsupervised, he did not have the operation but came to Britain, entering as a tourist, and then becoming an illegal immigrant.
Mrs Koneva said: “I am aware that he had serious criminal convictions and impending prosecutions in Poland.
“Something must be done to ensure that such a thing does not happen again.”
She also felt police would never catch her daughter’s killer.
Two months after Katerina’s killing, Princess Diana died in Paris. Public interest switched away from the murder of a schoolgirl in London.
Two years later the senior officer in the case, Detective Superintendent Hamish Campbell, was switched to the Jill Dando murder inquiry.
“That was when I felt the investigation was over. I felt very angry.”
For Mrs Koneva it is the end of a long vigil.
She attended court each day of Kunowski’s trial and collapsed outside court after hearing the pathologist’s evidence.
