Caroline Flack's mother has responded to a lawyer who told a UK Sunday newspaper that prosecutors were right to pursue the Love Island presenter's trial.
Ed Beltrami, who was the head of the Crown Prosecution Service's (CPS) north London division at the time, told the Wales on Sunday newspaper that he could not just do what he thought would be popular.
The TV presenter died in February at the age of 40, before the trial could take place.
Her mother, Chris Flack, said in a statement to her local newspaper the Eastern Daily Press: "It is deeply regrettable that Mr Beltrami could not have let my beautiful daughter rest in peace.
"It is as regrettable that he should choose to repeat some of the untruths about my daughter.
"My daughter was unable to defend herself during her life and is unable to do so now. Shame on you."
Flack, who grew up in Norfolk, died at her London home while awaiting trial on an assault charge for an alleged attack on her boyfriend Lewis Burton.
Mr Beltrami said: "You've got to do what you think is right. You cannot do what you think is popular."
He added that when the decision was taken to proceed with the case, "you have absolutely no idea that the defendant is going to take her own life".
Chris Flack said: "Mr Beltrami says that the CPS 'had no idea' that my daughter may take her life when they decided to continue the case against her.
"If that is true then the CPS ignored the correspondence from my daughter's solicitors and a psychologist's report warning of just that possibility.
"It also ignores the fact that my daughter had cut herself so badly the night of the incident for which she was arrested that she was taken to two different hospitals and there were concerns for her life.
"How can you claim to have 'no idea' that someone may take their life when they have already attempted to do so because of the events in question?
"Does Mr Beltrami claim to be ignorant of these facts or is he just ignoring them?
"The CPS were fully aware of these matters and the risk when they decided to continue the prosecution."
