The beloved comedian Martin Short has spent decades making audiences laugh, but this week his family is facing unimaginable grief. His daughter, Katherine Hartley Short, died on February 23, 2026, at the age of 42, according to a statement shared with the media. Authorities reportedly conducted a welfare check at her Hollywood home after a friend grew concerned, and she was later found deceased. People close to the situation indicated her death was the result of suicide. In a brief statement, the Short family expressed devastation and asked for privacy during this painful time, noting how deeply loved Katherine was and how her warmth and compassion touched many lives. Known for fiercely protecting his children from the spotlight, Martin had always kept family matters private, making the news all the more shocking to fans who admired his devotion as a father.

Katherine built a life centered on helping others. A graduate of New York University and later the University of Southern California, she became a licensed clinical social worker specializing in mental health care. She worked with veterans, supported individuals facing complex diagnoses, and advocated for reducing stigma around mental illness. On her former professional website, she openly acknowledged her own struggles and shared how her service dog, Joni, provided support—an honest reminder that even caregivers need care. Her passing has prompted renewed conversations about mental health, emphasizing that education and resources do not always shield someone from deep personal pain. In the wake of the tragedy, Martin and longtime collaborator Steve Martin postponed an upcoming performance as the family mourns.
