Robert, who was the only child of Mary and her husband Robert Cosby Sr., had been open about his struggles with addiction and related legal issues in the years leading up to his tragic death. His mother expressed her heartbreak in a statement, saying, “Our hearts ache, but we take comfort in God’s promise and in knowing he is finally at peace.”
During Season 5 of the reality show, Robert Jr. candidly discussed his battles with substance abuse, revealing to Mary that he had sought help in rehab after years of struggling. He first encountered legal issues in 2022 when he was arrested for driving under the influence (DUI), eventually pleading guilty to the charge while additional counts were dismissed. This incident marked the beginning of what would become a difficult path filled with personal challenges.
In an emotional episode that aired in late 2024, Robert Jr. shared his experiences with addiction, disclosing that he began using prescription drugs and recreational substances at the age of 16. He stated that substances offered an escape, saying, “Sometimes, I feel like… just life is like this chicken without seasoning. But when I get high, it’s like seasoning.” This stark metaphor described how his addiction escalated, including experimenting with heroin during his struggles.
Mary openly supported her son throughout his tumultuous journey, often publicly reflecting on the challenges they faced. Recognising the difficulties of addiction, she encouraged Robert Jr. to remain focused on his recovery wishes. “I have hope and I believe in him… He’s got all the will and the support,” she remarked during an interview in September 2025.
Just a month after his heartfelt discussion with Mary, Robert entered a rehabilitation programme and successfully completed a month-long stay away from home. Mary expressed pride in her son’s progress, noting at the time that he was doing “so good” and had come out transformed. However, the road to sustained recovery proved challenging for Robert Jr., who faced subsequent arrests.
In September 2025, he was detained on several charges, including criminal trespass and assault. Mary’s perspective on this arrest was mixed; while devastated, she also perceived it as “a blessing in disguise,” believing that her son needed the experience to understand the consequences of his choices. Despite his challenges, Robert Jr. remained hopeful and upbeat, stating that while he was not where he wanted to be, he was certainly making improvements.
Regrettably, Robert faced further legal troubles, including a series of additional arrests in late 2025. These culminated in a sentencing in February 2026, just weeks before his untimely death. Following his sentencing, he was released and was placed on probation, reportedly working on recovery.
Tragically, Robert’s life ended on February 23, 2026. His passing has left a profound impact on his family and the community. Bravo Media, the company behind “The Real Housewives of Salt Lake City,” expressed their sorrow over his death, referring to him as a “cherished member of our family.”
In their official statement, Mary and Robert Sr. highlighted their grief while maintaining faith in the divine. They conveyed gratitude for the prayers and support received during this painful time. The couple’s message underscored their enduring love for their son and the comfort drawn from their shared faith.
Mary Cosby’s tragic experience serves as a poignant reminder of the far-reaching consequences of addiction and mental health struggles. As friends, family, and fans come to terms with the loss, resources and support systems remain vital for those dealing with similar challenges.
