According to Fox News, a joint statement from the medical examiner's office and the Metropolitan Police Department said Graham was pronounced dead at George Washington University Hospital at 10:23 p.m. Saturday, July 11, 2026. An autopsy was performed the following day.

The medical examiner's office said the preliminary findings indicate Graham suffered an aortic dissection caused by arteriosclerotic cardiovascular disease.
Officials stressed that the findings are preliminary, with toxicological and microscopic testing still underway before a final death certificate is issued.
According to the Mayo Clinic, an aortic dissection is a tear in the inner layer of the aorta — the body's largest artery — that allows blood to flow between the vessel's layers. The condition is a life-threatening medical emergency that can cause severe internal bleeding or organ damage.

Arteriosclerotic cardiovascular disease is caused by plaque buildup inside the arteries, reducing blood flow and increasing the risk of serious heart and vascular complications.
