Martin Short’s Daughter Katherine Passes Away at 42 — Her Final Public Photo With Loving Dad

A heartbreaking loss has struck Martin Short and his family. In the wake of the tragedy, a once-joyful public photo of the comedian and his daughter is now drawing renewed attention.

Katherine Hartley Short, daughter of “Only Murders in the Building” star Martin Short, has died at 42. Her family confirmed the news in a statement expressing profound grief.

Authorities have also released details surrounding the circumstances of her death.

Short Family Speaks Out

A spokesperson for Martin Short confirmed the heartbreaking news in a statement to Good Morning America:

“It is with profound grief that we confirm the passing of Katherine Hartley Short. 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.”

In the hours that followed, authorities provided additional details about what had occurred.

Details of the Emergency Response

According to GMA, police in Los Angeles responded to Katherine’s residence at 6:43 p.m. on Monday, February 23, 2026, following a report of a possible suicide. Upon arrival, officers and paramedics discovered a deceased woman and launched an investigation.

The Los Angeles Fire Department separately confirmed that crews had been dispatched to the home after receiving reports of a shooting.

Further details about the emergency response were later reported by the Daily Mail, which obtained audio of the 911 call tied to Katherine’s death. The recording reportedly captured a dispatcher relaying critical information to first responders.

In the call, a Fire Department dispatcher stated that the wound appeared to be self-inflicted. The caller was described as being with Katherine but “unable to enter the bedroom.”

A department spokesperson said crews arrived at approximately 6:41 p.m., though officials declined to identify the individual involved, citing privacy concerns. The impact of the tragedy began to reach beyond the family’s private grief.

Milwaukee Show Postponed

Amid the tragedy, an upcoming live performance featuring Martin and his longtime collaborator Steve Martin will no longer take place as scheduled.

According to a notice posted on the Pabst Theater Group website, the duo’s February 27 show in Milwaukee has been postponed due to “unforeseen circumstances.”

Their statement confirms that tickets will be honored for a future rescheduled date and that further updates will be shared when available. Ticket holders were directed to contact tickets@ptglive.com with any questions.

The show, titled “The Best of Steve Martin & Martin Short,” is described as a fast-paced, comedic showcase highlighting the duo’s decades-long friendship and on-stage chemistry, a partnership that began with the 1986 film “Three Amigos” and evolved into a touring collaboration that launched in 2015.

For now, however, the focus remains on family as Martin navigates an intensely personal loss.

A Father Who Put Family First

The tragedy comes at a time when Martin has often spoken about keeping his personal life grounded and balanced. In a 2022 interview with People, he reflected on choosing family over constant career ambition.

“And I think it’s unbecoming at 72 to be 100 percent obsessed with your career. My life, my children, my friends — I have great joy in that,” Martin said. Those words now resonate even more deeply.

In September 2021, Katherine appeared with her father at the HempHera Kosmetikos pre-Emmy luxury lounge in West Hollywood. It marked the last time she was photographed publicly with Martin.

For those looking back at Katherine’s life beyond this tragic moment, her journey — both personal and professional — reveals a path shaped by compassion, education, and quiet dedication.

Katherine Elizabeth Short Is a Two-Time Graduate

Katherine attended New York University, where she studied Psychology and Gender Sexuality. According to her now-defunct website, she graduated in 2006 and pursued a Master’s at the University of Southern California School of Social Work, which she attained in 2010.

During her Master’s studies, Katherine built her work profile. She interned at a pro-bono law firm, providing family therapy, advocacy, and case management for various disadvantaged groups, including foster youth, low-income families, and political refugees.

She then trained at the West LA Veterans Administration, offering individual and group psychotherapy for veterans with schizophrenia and bipolar disorder. After graduating, she worked at Resnick Neuropsychiatric Hospital for four years.

After passing her licensure exam, Katherine moved to Camden Center, where she offered group and individual cognitive behavioral therapy. She practiced privately in Los Angeles, where she specialized in treating anxiety, depression, suicidality, and more.

Katherine Elizabeth Short Lost Her Mother in 2010

In August 2010, news broke that Katherine’s mother, Nancy, had passed. At the time, her family kept the details of her death private, but her father later revealed she died fighting ovarian cancer. Concerning how his kids grieved, Martin noted they each had their way of dealing with the loss.

“One deals with it more aggressively; someone else maybe doesn’t talk about it, but it doesn’t mean that they’re not all grieving,” he said. In a 2014 interview, Martin, who was once assumed gay, shared how he, Katherine, and her siblings celebrated Nancy’s life.

He explained that his wife had said she didn’t want a funeral or a memorial service; she wanted her life celebrated, even suggesting a party. Despite the heartache of losing her, Martin honored her wishes, throwing a party with close friends and family at their lakehouse.

Katherine Elizabeth Short Would Have Gone to Broadway

It’s unclear when her interest in the arts began, but Katherine played piano and wrote her own music. At 22, she reportedly expressed her desire to join Broadway; however, it appears to have fizzled.

Sharing insight about her childhood with Conan O’Brien, her dad said he encouraged Katherine and her siblings to go into show business. However, only her brother, Oliver Patrick Short, joined the entertainment industry, but as a producer in sports.

Katherine’s other brother, Henry Sayter Short, is a Veterinary Assistant. Speaking about raising them, her dad joked, “You must be sensitive to your children’s needs and make sure your personal assistant fulfills them,” saying that’s how he approached “Hollywood parenting.”

As the family moves through this difficult period, public attention continues to center on Katherine’s life and legacy. In the end, the memories captured over the years remain a lasting reminder of the bond she shared with her father.
