'RHOSLC' Mary Cosby's Son Robert Jr. Passes Away at 23 — What We Know

A sudden loss has shaken the "Real Housewives of Salt Lake City" world. A 23-year-old died after a reported medical emergency evolved into something much more grave.

A devastating turn of events has left one "Real Housewives of Salt Lake City" (RHOSLC) star facing every parent's worst nightmare.

Utah authorities were dispatched late at night to a medical emergency involving someone close to Mary Cosby, but the situation soon escalated into a death investigation.

According to TMZ, Salt Lake City police responded Monday night, February 23, 2026, to a report of a "full arrest/medical emergency" involving a 23-year-old man.

Authorities say the situation evolved into a death investigation after officers arrived, with a possible overdose noted in the initial response.

Firefighters and paramedics were also dispatched. Officials have not confirmed an official cause of death.

In a statement shared with the outlet, Mary and her husband, Robert Sr., said their "beloved son Robert Jr. has been called home to the Lord," adding that despite their heartbreak, they find comfort in faith and in believing "he is finally at peace."

Tragedy struck after a difficult stretch in Robert Jr.'s life. Just months ago, his wife, Alexiana Smokoff, filed for divorce, following their August 2022 courthouse wedding — a reveal that surprised viewers when it surfaced on "RHOSLC."

On the show, Mary also confronted concerns about her son's alleged substance use.

Beyond reality TV, Robert faced legal trouble in recent years, including a September arrest on charges such as trespassing and assault, along with a prior conviction for driving under the influence (DUI). He was released from prison in February.

As the Bravo community mourns one devastating loss, another Hollywood family is facing heartbreak of its own.

Martin Short's daughter, Katherine Short, has died at the age of 42. According to TMZ, she died from a self-inflicted gunshot wound.

Law enforcement sources told the outlet that officers with the Los Angeles Police Department and members of the fire department responded to her home in the Hollywood Hills shortly after 6:40 p.m. on Monday. She was found deceased at the scene in what quickly became a heartbreaking tragedy.

A Family Devastated by Unimaginable Loss

A representative for the family confirmed her passing in a statement to TMZ, saying the family is overwhelmed with grief, devastated by the loss, and asking for privacy as they navigate this painful time. The grieving father also shared a message on Facebook, laying bare his broken heart in an emotional tribute that stunned fans.

He wrote, "It is with broken hearts that we share the passing of our beloved daughter, Katherine Hartley Short. There are no words for the depth of this loss. Our family is devastated, and we ask for privacy as we grieve this unimaginable heartbreak. Katherine was the light of our lives full of warmth, kindness, and a joy that touched everyone she met. That light will never fade in our hearts. Forever loved. Forever our daughter."

Katherine was the eldest child of Martin and his late wife, Nancy Dolman, who died in 2010 from ovarian cancer — another profound loss that deeply affected the family.
