Relatives of a missing boy's mother who killed herself after being aggressively questioned by CNN's Nancy Grace filed a wrongful death suit Tuesday, claiming the talk-show host caused severe emotional distress that led to the suicide.

"In (the lawsuit), Melinda's parents claim Nancy Grace and her producers lied to get their daughter on the show and that they are accountable for her suicide," Local 6's Jessica D'Onofrio said. "The suit claims Grace's spitfire cross-examination of the young mother pushed Melinda to the brink. They said Grace was the judge, jury and executioner."

Grace came under fire for her aggressive questioning of Duckett on the day before she committed suicide on Sept. 8 as crews searched for her missing son, Trenton.

One week after Duckett ended her life, Grace went on air to defend her "fist-pounding" interview of the young mother.

"You look for somebody to blame," Grace said. "You look hard. I do not feel that our show is to blame for what happened to Melinda Duckett. Melinda committed suicide before that interview aired."

However, now Grace is about to be sued for wrongful death by Duckett's parents, Jay and Beth Eubank, Local 6 News reported late Monday.

The family hired a Palm Beach law fire to file the lawsuit Tuesday, according to the report.

"What we are saying is that Nancy Grace's actions have led to Melinda's suicide," Attorney Kara Skorupa said.

The parents claim the Nancy Grace show misled Duckett into doing the interview, saying the 21-year-old was convinced to go on the national broadcast under false pretenses.

According to the family's attorneys, producers told Duckett that the purpose of the questioning was to drum up awareness of her son's disappearance.

However, they said Grace interrogated and accused Duckett of a crime by implication, according to the report.

"That conduct in combination with the questions she asked in the family's view put Melinda over the edge," Attorney Paul Deratany said.

A CNN Headline News spokesperson said, "While we have no comment on pending litigation, we stand by Nancy Grace and fully support her, as we have from the beginning of this matter."

Attorneys for the Eubanks said they are seeking monetary damages but have not decided on an amount.
