Hollywood is reeling after heartbreaking news struck the family of beloved comedian and actor Martin Short.
Katherine Hartley Short, the 42-year-old daughter of the Only Murders in the Building star, was found dead Tuesday, according to TMZ. Law enforcement sources told the outlet that her death was the result of a self-inflicted gunshot wound.
The Short family confirmed the devastating loss in a statement.
“It is with profound grief that we confirm the passing of Katherine Hartley Short,” a family representative shared. “The Short family is devastated by this loss and asks for privacy at this time. Katherine was beloved by all and will be remembered for the light and joy she brought into the world.”
Short, 75, adopted Katherine in 1983 with his late wife, Nancy Dolman. The couple, who were married for 30 years until Dolman’s death from ovarian cancer in 2010, also adopted two sons: Oliver Patrick, 39, and Henry Hayter, 36.
While her father built a legendary comedy career spanning decades, Katherine chose a path centered on healing and advocacy.
She graduated from New York University in 2006 with a degree in psychology and gender sexuality studies. She later earned a master’s degree in social work from the University of Southern California in 2010.
Katherine went on to work as a licensed clinical social worker in Los Angeles, dedicating her career to supporting individuals struggling with mental health challenges. She worked in private practice and previously spent four years at UCLA’s Resnick Neuropsychiatric Hospital. She also worked with the Camden Center, a dual-diagnosis outpatient treatment program specializing in psychiatric, addiction, and eating disorders.
In addition to her clinical work, she contributed part-time to Amae Health, offering psychotherapy and support groups. She was also involved with Bring Change 2 Mind, a nonprofit focused on eliminating the stigma surrounding mental illness.
Though she largely stayed out of the spotlight, Katherine occasionally accompanied her father to industry events and red carpets over the years.
The tragedy marks another profound loss for Short and his family. After Dolman’s passing in 2010, the actor spoke candidly about grief and resilience in a 2012 interview with The Guardian.
“It’s been a tough two years for my children,” he said at the time. “This is the thing of life that we live in denial about, that it will ever happen to us or our loved ones, and when it does you gain a little and you suffer a little. There’s no big surprise.”
Now, the family is once again facing unimaginable sorrow.
