Virginia Giuffre’s father has broken his silence, rejecting the official narrative surrounding his daughter’s sudden death and demanding a federal investigation.

Sky Roberts says Virginia was making plans for the future and had “no reason” to end her life—calling the suicide ruling premature and deeply suspicious.

Roberts cited past social media posts from Giuffre saying she had no suicidal ideations, telling TMZ in an article published April 28 that federal authorities must investigate the matter.

The family of Virginia Giuffre has also called for an investigation, and shared a handwritten letter she wrote shortly before her death in which she spoke about the future and asserted that her “voice will not be silenced”.

The letter states: “Mothers, Fathers, Sisters, and Brothers need to show the battle lines are drawn, and stand together to fight for the future of victims. Is protesting the answer? I don’t know. But we’ve got to start somewhere.”

Likewise, Giuffre’s lawyer said she has “big question marks” about the Giuffre’s sudden and unexpected death.

“When I got the phone call, I was like, ‘Are you joking?’” Karrie Louden told The Sun in an interview published April 28. “Because there was no sign that that was something she was considering.”

Louden argued that while Giuffre was “looking forward to things in the future,” and was making plans with her children. “She wanted to renovate this house and all sorts of things like that.”

Lawyer Karrie Louden “could not believe” the news that Giuffre allegedly took her own life.

Giuffre’s death came weeks after she said that she had suffered a devastating car crash, with doctors saying she had only days left to live.

“I’ve gone into kidney renal failure,” Giuffre, who shared three kids with estranged husband Robert Giuffre, wrote on Instagram March 30. “I’m ready to go, just not until I see my babies one last time, but you know what they say about wishes. Shit in one hand and wish in the other & I guarantee it’s still going to be shit at the end of the day.”

However, Giuffre was ultimately released from the hospital, her rep confirmed to People April 7.
