The circumstances of her "suicide" are unclear, what the alleged method of suicide was, or any explanation why.

She divorced an allegedly abusive husband of 22 years in January 2025. And he apparently got custody of her children (despite being a domestic abuser?) who she was separated from, and that in her posts her ex husband was "poisoning them against [her] ".
She was in a recent car accident with a bus March 27th, that allegedly she said online a doctor had told her the injuries sustained in the accident left her "days left to live. "
But the driver of the bus that hit her car said her injuries were not that serious, that a 70 year old lady was driving, and Giuffre was in the passenger seat and the driver "didn't even notice her", let alone see she had injuries. And a month after the accident she had not died... when she suddenly committed suicide?

Police were investigating, but did not appear to consider it a suspicious death.
And no cause of death, or the circumstances of who or when her body was found, were discussed. But the stories of her suicide appear to have been first reported 3 days ago, as of this writing.

All that is said is she was living in a $1.9 million dollar mansion in Perth, Australia, at the time of her death (presumably purchased from her $22 million settlement awarded from Prince Andrew, that she previously lived in with her husband and children), and she had 3 children who were very important to her. If she were dying from accident injuries, or if she were aggrieved by her divorce and the loss of her children, I would think that she would want to be with her children before she died.
But I guess this is still a new event and still being fully investigated.
