A Sudden Loss for Hollywood

A pulmonary embolism occurs when a blood clot blocks an artery in the lungs. This was identified as the direct cause of death for the 71-year-old actress. Underlying this was the presence of colorectal cancer.

O’Hara was widely recognized for her Emmy-winning portrayal of the dramatically unaware matriarch, Moira Rose, in “Schitt’s Creek.” She also achieved iconic status for her role as Macaulay Culkin’s mother in the beloved films “Home Alone” and its sequel.
