Catherine O’Hara’s cause of death revealed

Catherine O’Hara, the celebrated actress known for her roles in “Schitt’s Creek,” “Beetlejuice,” and “Home Alone,” died on January 30th. The Creative Artists Agency confirmed her passing, marking a significant loss for the entertainment industry.

A Complex Medical Picture

While the County of Los Angeles Department of Public Health initially listed a pulmonary embolism as the immediate cause of death, further information revealed rectal cancer as an underlying factor, according to reports. This suggests a complex medical situation contributed to the tragic outcome.

Following her death, O’Hara was cremated, and her remains were received by her husband, Bo Welch, as indicated by her death certificate. This fulfills a final arrangement made by the actress and her family.

A Long and Illustrious Career

O’Hara’s career spanned decades, encompassing iconic films and television series. Beyond “Beetlejuice,” “Home Alone,” and “Home Alone 2,” she recently appeared in “The Last of Us” with Pedro Pascal and “The Studio” alongside Seth Rogen, demonstrating her continued engagement with contemporary projects.

The Los Angeles Fire Department responded to a call at O’Hara’s Los Angeles home at 4:48 a.m. Local time on the day of her death, transporting her to the hospital in “serious” condition. This indicates a rapid escalation of her health crisis.

Pre-Existing Condition and Final Days

O’Hara lived with situs inversus, a rare condition where internal organs are mirrored from their normal arrangement. While typically harmless, this condition can complicate diagnoses due to atypical symptom presentation. Sources reported that some friends were “in complete shock” following her death, and that she may have been aware of her condition, though many close to her were kept in the dark during her final days.

In the months leading up to her death, O’Hara was seen at public events, including the Angel Awards in October 2025, where she was described as looking “very slender” but “in great spirits.” Two weeks before her passing, she appeared at an event for Supermodels Unlimited magazine and was reported to have “looked healthy.”

Catherine O’Hara is survived by her husband, Bo Welch, whom she married in 1992, and their two sons, Matthew and Luke, as well as six siblings: Michael O’Hara, Mary Margaret O’Hara, Maureen Jolley, Marcus O‘Hara, Tom O’Hara and Patricia Wallice.
