LOS ANGELES (AP) Catherine OHara died from a pulmonary embolism, with cancer as the underlying cause.
A Los Angeles County death certificate issued Monday lists the pulmonary embolism, which occurs when a blood clot blocks an artery in the lungs, as the immediate cause of the actors Jan. 30 death at age 71. Rectal cancer was the long-term cause.
The oncologist who signed off on the certificate indicated that he had been treating OHara since March of last year, and last saw her on Jan. 27. She died at a hospital in Santa Monica, California.
The beloved Canadian-born comic actor and SCTV alum starred as Macaulay Culkins mother in two Home Alone movies and won an Emmy as the dramatically oblivious wealthy matriarch Moira Rose in Schitts Creek.
