John Ritter, best known for "Three's Company" and "8 Simple Rules," died on September 11, 2003 from an aortic dissection. Years later, in a 2024 interview, co‑star Katey Sagal recalled the sudden loss and noted her brief testimony in a 2008 wrongful‑death trial related to the actor’s death.

In August 2026, Ritter’s widow, actress Amy Yasbeck, filed a £10 million negligence lawsuit against Providence Saint Joseph Medical Center and two doctors, alleging that an initial misdiagnosis of a heart attack delayed treatment for the aortic dissection and caused his death. The legal action adds a new dimension to the long‑standing public attention surrounding Ritter’s fatal incident.
