The official cause of death for Katherine Hartley Short, the eldest daughter of beloved actor and comedian Martin Short, has been formally determined by authorities. According to a death certificate issued by the Los Angeles County Department of Public Health, which was obtained and reviewed by the media outlet TMZ, Katherine died as a result of a self-inflicted gunshot wound to the head. The document additionally confirms that her remains have since been cremated.
Discovery at Hollywood Hills Residence
Katherine, who was 42 years old, was discovered deceased inside her Hollywood Hills home last Monday. Authorities responded to the residence after receiving a concerned call. The Los Angeles Police Department has verified that she was found behind a locked door within the property. At the scene, officers recovered a firearm and a personal note, though the specific contents of that note have not been disclosed to the public.
Timeline of Events and Police Response
Law enforcement sources speaking to TMZ indicated that Katherine had not been heard from for approximately 24 hours before a worried friend contacted the police. Officers were subsequently forced to breach the locked door to gain entry, where they then discovered her body. Homicide detectives who attended the scene conducted a preliminary investigation and concluded there were no indications of foul play involved in her death.
A close friend of Katherine's told TMZ that her behavior in the days immediately preceding her tragic death appeared completely normal, with no outward signs that she might be considering self-harm. This has added to the profound shock and confusion surrounding the incident.
Devastating Impact on Martin Short
The sudden and devastating loss has reportedly left her father, Martin Short, utterly heartbroken and reeling. TMZ reported that the 75-year-old comedian has been described as 'inconsolable' since his daughter's death and has largely withdrawn from public life in the aftermath.
In a clear sign of his grief, Short has canceled several scheduled comedy performances with his longtime collaborator, Steve Martin. He also did not attend the recent Actors Awards ceremony, where he had received a nomination for Outstanding Male Actor in a Comedy Series.
Katherine's Personal and Professional Life
Katherine was the eldest child of Martin Short and his late wife, actress Nancy Dolman, who passed away in 2010 after a battle with ovarian cancer. The couple had adopted Katherine along with their two sons, Oliver, 39, and Henry, 36.
A graduate of the University of Southern California, Katherine held a master's degree and worked professionally as a licensed clinical social worker. She was also actively involved with a mental health charity, dedicating herself to helping others. Friends later told the Daily Mail that while Katherine had privately faced difficult personal challenges, she was widely admired for her deep compassion and unwavering commitment to supporting those in need.
Final Public Appearance and Community Support
Katherine was last seen publicly with her father in 2023 when they celebrated her 40th birthday at Grandmaster Recorders in Hollywood. The celebratory gathering included a number of well-known friends and figures, such as Catherine O'Hara, Joni Mitchell, Kurt Russell, and Goldie Hawn.
Since the news of her death became public, several of Martin Short's close friends have reportedly visited him at his Los Angeles home to offer their personal support and condolences during this incredibly difficult time.
