Robert Cosby Jr.’s Final Years: Threats, Drugs and How Mary Was Involved
Robert Cosby Jr.’s Struggles with Drugs and Legal Issues
Robert Cosby Jr., son of Mary Cosby from The Real Housewives of Salt Lake City, experienced a series of tumultuous events in his final years that involved substance abuse, legal confrontations, and personal hardships. These challenges culminated in a tragic end, but the story of his struggles reveals much about the pressures he faced and the role his family played.
The first significant legal issue for Robert Jr. came in 2022 when he was arrested for driving under the influence (DUI). Authorities reported that he was operating a vehicle without a license and violating traffic laws. He eventually pleaded guilty to the DUI charge, leading to the dismissal of other related charges. This incident marked the beginning of a series of legal and personal troubles that would follow.
In August 2022, a police investigation into a hit-and-run incident brought law enforcement to the Cosby family home. The vehicle involved was registered to Mary Cosby, and during questioning, Mary allegedly refused to provide information and accused officers of racial profiling. This confrontation highlighted the tense atmosphere surrounding the family during this period.
Adding to the complexity of Robert Jr.’s life, he secretly married Alexiana Arian Smokoff in August 2022. Mary Cosby only learned about the marriage nearly a year later during a conversation on RHOSLC, expressing her concerns about her son’s readiness for such a commitment. The marriage, fraught with difficulties, eventually ended in divorce filings in late 2025.
Overdose Incidents and Hospitalizations
One of the most alarming episodes in Robert Jr.’s final years was his overdose on Valentine’s Day 2023. Emergency responders found him unconscious at his parents’ home and performed life-saving measures before transporting him to the hospital. This incident was a stark indicator of his ongoing battle with substance abuse.
Further reports revealed that Robert Jr. and his wife were involved in a domestic violence incident in May 2024, allegedly triggered by his drug use. The victim, later identified as Smokoff, accused Robert Jr. of physical assault after she flushed his drugs down the toilet. Despite the severity of the allegations, Mary Cosby denied knowledge of any physical altercations between her son and daughter-in-law.
Robert Jr.’s struggles with addiction were candidly discussed during a 2024 episode of RHOSLC, where he admitted to using various substances, including Xanax, Adderall, acid, molly, and cocaine. He revealed feelings of despair and suicidal thoughts but credited his mother as a source of support that kept him going.
Rehabilitation and Continued Legal Battles
In late 2024, Robert Jr. completed a month-long rehabilitation program, which Mary Cosby described as a positive turning point. However, his legal troubles persisted. In September 2025, he was arrested for trespassing and assault after attempting to enter his father-in-law’s home and allegedly assaulting someone on the property. He faced multiple charges, including criminal trespassing, assault, and violation of court orders.
Despite these challenges, Mary viewed the arrest as a necessary intervention for her son’s well-being. Robert Jr. pleaded guilty to several charges in November 2025, coinciding with his wife’s filing for divorce. The legal proceedings continued into early 2026, with Robert Jr. denying some allegations and attributing erratic behavior to drug-induced psychosis.
Mary Cosby’s Role and Emotional Journey
Throughout these difficult years, Mary Cosby remained deeply involved in her son’s life, balancing public scrutiny with private grief. She openly discussed Robert Jr.’s addiction and mental health struggles, expressing both heartbreak and hope. During the RHOSLC season 6 reunion in January 2026, Mary tearfully acknowledged the pain of seeing her son incarcerated but emphasized her belief that he was in a safer place away from substance abuse.
Mary’s public statements and actions reflected a mother’s enduring love amid tragedy. She celebrated Robert Jr.’s release from jail in February 2026, sharing a heartfelt message on social media. Her involvement extended to legal matters as well, with her family’s attorney addressing false allegations and focusing on healing.
The Tragic End and Family Tributes
Tragically, Robert Cosby Jr. was found dead at his parents’ Utah home in February 2026 from a suspected overdose. Emergency responders arrived after a call reporting an unconscious male who was not breathing. Despite efforts to revive him, Robert Jr. was pronounced dead at the scene at just 23 years old.
In the wake of his passing, Mary and Robert Sr. Cosby issued a statement expressing their sorrow and faith. They described their son as having been “called home to the Lord” and found solace in the belief that he was finally at peace. The family’s attorney shared that the Cosbys were struggling to comprehend the loss of someone so young and vibrant, mourning the absence of Robert Jr.’s warm spirit and kind heart.
