According to official statements from the Los Angeles Police Department, Short reached out to a close personal friend who lives near Katherine’s West Hollywood residence after he failed to reach her for over 48 hours through calls and text messages, asking the friend to conduct an informal welfare check to make sure she was safe. The friend arrived at Katherine’s ground-floor apartment on the afternoon of May 8, received no answer after repeated knocks, and contacted building management to access the unit, where they found Katherine unconscious on her living room couch. Emergency responders were dispatched immediately, and paramedics pronounced her dead at the scene shortly after arrival. Initial on-site investigations by law enforcement found no signs of forced entry, physical trauma, or suspicious activity in the apartment, leading authorities to note that no foul play is suspected at this stage of the investigation. The Los Angeles County Coroner’s Office took possession of Katherine’s body the same day to conduct a full autopsy and toxicology screening, as standard procedure for unexpected, unattended deaths. As of press time, official autopsy details have not been released to the public, with a coroner’s spokesperson noting that full toxicology results typically take between four and six weeks to process, and a formal cause of death will be listed as “pending” until all lab work is completed and reviewed by board-certified medical examiners. Katherine Elizabeth Short was the oldest of three children Martin Short shared with his late wife, actress Nancy Dolman, who passed away from ovarian cancer in 2010. Short’s representative released a brief statement on behalf of the family last week, asking for full privacy as they mourn their loss and noting that no further comments will be provided until the official coroner’s report is finalized. Fans and fellow Hollywood figures have flooded Short’s social media pages with messages of support in the days following the news, with many highlighting the actor’s long history of public resilience through personal loss, including the deaths of his parents and older brother during his teenage years, as well as his wife’s passing 14 years ago.
