Marie Cosby, The Real Housewives of Salt Lake City star, mourns the devastating loss of his only child, Robert Jr., who died at age 23 on February 23, 2026.
Mary had hoped that prison would “directly scare” her son, who had struggled with drug addiction and legal problems.
Robert Jr. served time in late 2025 for assault and violating a protection order.
He was released earlier this month.
A few weeks later, police responded to a 911 call about a possible overdose.
Despite administering Narcan, Robert Jr. was found unconscious and not breathing.
Speaking on Andy Cohen liveBravo host Andy Cohen described the tragedy as “every parent’s worst nightmare.”
He recalled how Mary tried to guide her son with love and patience.
He noted that during the RHOSLC Season 6 reunion Robert Jr. was in prison and Mary had hoped that this experience would help him change his life.
After his death, Mary and her husband Robert Sr. released a statement: “Our beloved son, Robert Jr., has been called home to the Lord. Although our hearts ache, we are comforted by God’s promise and knowing that he is finally at peace.”
Cosby family attorney Clinton Simms described Robert Jr. as someone with “a warm spirit, humor and a kind heart” who will be greatly missed.
Mary’s grief is shared by fans and fellow Bravo stars, who have flooded social media with condolences and tributes.
