Martin Short’s daughter, Katherine, dead by apparent suicide at 42

Martin Short’s daughter, Katherine, died on Monday by an apparent suicide. She was 42.

“It is with profound grief that we confirm the passing of Katherine Hartley Short,” a rep for the “Only Murders in the Building” star confirmed to Page Six Tuesday.

“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.”

The social worker was reportedly found dead with a self-inflicted gunshot wound at her Hollywood Hills, Calif., home on Monday around 6 p.m. local time, per TMZ.

“At 6:41 p.m., we responded to a reported shooting at that address,” the Los Angeles Fire Department told Page Six, confirming they received a call to 911.

“Death was reported of a female.”

Katherine was the adopted daughter of the actor, 75, and his late wife, Nancy Dolman, who died from cancer in 2010.

Short and Dolman, who were wed for 30 years, also adopted sons Oliver Patrick, 39, and Henry Hayter, 36, together.

Katherine, meanwhile, graduated with her psychology and gender sexuality studies bachelor’s degree from New York University in 2006, per People.

Then, in 2010, she earned her master’s degree in social work from the University of Southern California.

The businesswoman worked as a social worker for a private practice and part-time at the Amae Health clinic, an outreach group that provides psychotherapy, leading up to her death.

Additionally, Katherine was involved with Bring Change 2 Mind, a charity that strives to reduce the stigma surrounding mental health.

For the most part, Katherine has remained out of the spotlight, but has attended a few events with her famous father over the years.

Their last public sighting was in 2023 for Katherine’s 40th birthday celebration at Grand Master Recorders in Hollywood.

Before then, the father-daughter duo stepped out together at a 2021 pre-Emmy bash hosted at the Kimpton La Peer Hotel in West Hollywood, Calif.

Short also brought Katherine to an afterparty for the Los Angeles production of “The Producers” in 2003 and to Bette Midler’s New York Restoration Project in 2005.
