Chad Lowe Daughter Fiona Cause of Death Update: What Happened to 13-Year-Old? ‘We Are Deeply Heartbroken’

Actor Chad Lowe and his wife Kim Painter are mourning the death of their 13-year-old daughter, Fiona Hepler Lowe. The family confirmed the news in a statement shared with PEOPLE, describing Fiona as a loving and creative child who was deeply cherished by her parents and sisters.

What was Fiona Lowe's cause of death?

As of the latest reports, the cause of Fiona's death has not been disclosed publicly.

Neither Chad Lowe nor Kim Painter has provided details about what happened to their daughter. The family's statement focused on remembering Fiona and asking for privacy rather than discussing the circumstances of her death. Entertainment Weekly also reported that the cause remained undisclosed as the story continued to develop.

Because the family has not announced a cause, claims circulating online about the circumstances of Fiona's death should be treated cautiously.

‘We are deeply heartbroken’

In a statement, the Lowe family said they were “deeply heartbroken” by Fiona's death.

They remembered her as a loving, smart and creative young girl who loved to dance. The family also said she was adored by her sisters and deeply loved by her parents, describing her as “the light of our lives.”

The family has asked for prayers and privacy as they deal with the loss.
