Robert Cosby Jr.’s Final Years: Threats, Drugs and How Mary Was Involved

Robert Cosby Jr.’s Struggles with Addiction and Legal Issues

Robert Cosby Jr., son of Mary Cosby from The Real Housewives of Salt Lake City, faced a series of challenges in his final years that painted a complex and heartbreaking picture. His battles with drug addiction, encounters with law enforcement, and strained family relationships culminated in a tragic end that left many searching for answers.

The first notable legal incident occurred in 2022 when Robert Jr. was arrested for driving under the influence (DUI). Reports indicated that he was operating a vehicle without a license and violated traffic laws. He pleaded guilty to the DUI charge, which resulted in other charges being dropped. This incident marked the beginning of a series of legal troubles that would shadow his final years.

In August 2022, police investigated a hit-and-run incident involving a vehicle registered to Mary Cosby. When officers approached Mary at her home, she refused to provide information about the driver and accused the police of racial profiling. This confrontation highlighted the tension between the Cosby family and law enforcement during this period.

Adding to the complexity of his personal life, Robert Jr. secretly married Alexiana Arian Smokoff in August 2022. Mary only learned about the marriage nearly a year later during a conversation on RHOSLC. She expressed concern over his readiness for marriage, emphasizing the responsibilities that come with such a commitment.

Overdose Incidents and Hospitalizations

Robert Jr.’s struggles with substance abuse were severe and well-documented. On Valentine’s Day 2023, emergency responders were called to the Cosby family home after Robert Jr. was found unconscious due to a suspected drug overdose. Medical personnel administered life-saving measures, including chest compressions, before transporting him to the hospital. This incident was a stark reminder of the severity of his addiction and the ongoing battle he faced.

Despite efforts to support him, including a month-long rehabilitation stint in late 2024, Robert Jr.’s addiction issues persisted. His openness about his substance use on RHOSLC revealed his use of Xanax, Adderall, cocaine, and other drugs, as well as his mental health struggles. He admitted to feeling hopeless at times, with Mary being his primary source of support.

Domestic Violence Allegations and Legal Consequences

In May 2024, Robert Jr. was allegedly involved in a domestic violence incident with his wife, Alexiana Smokoff. According to police reports, the altercation began after Smokoff flushed Robert Jr.’s drugs down the toilet. The situation escalated, resulting in physical violence that left Smokoff unconscious. She did not report the incident until November 2025, citing pressure from the Cosby family to avoid law enforcement involvement.

Robert Jr. was later arrested in September 2025 for trespassing and assault related to an incident at his father-in-law’s home. He faced multiple charges, including criminal trespassing, assault, and violation of court orders. In November 2025, Smokoff filed for divorce, further complicating Robert Jr.’s personal and legal challenges.

Despite these allegations, Robert Jr. denied the accusations and filed court documents disputing the claims, suggesting they were fabricated in retaliation for the failed marriage. However, his ongoing legal battles and substance abuse issues continued to weigh heavily on him.

Mary Cosby’s Role and Emotional Journey

Mary Cosby’s involvement in her son’s life during these tumultuous years was both supportive and complex. She publicly acknowledged Robert Jr.’s addiction struggles and the impact they had on their family. In interviews and on RHOSLC, Mary expressed her heartbreak and determination to help her son overcome his challenges.

Mary was present during many critical moments, including Robert Jr.’s overdose in 2023 and his emotional confessions about drug use and mental health. She openly shared her fears and hopes, emphasizing her love and commitment to her son despite the difficulties.

The tension between Mary and law enforcement, particularly during the hit-and-run investigation, also underscored the protective stance she took regarding her family. Her refusal to cooperate with police and accusations of racial profiling reflected the broader challenges faced by the Cosbys in navigating these crises.

The Final Months and Legacy

Robert Cosby Jr.’s final months were marked by continued legal struggles and attempts at rehabilitation. He was released from jail in February 2026 after serving time related to his various charges. Tragically, just weeks later, he was found dead at his parents’ home from a suspected overdose.

Mary and Robert Sr. Cosby publicly mourned their son, describing his passing as a profound loss and a moment of deep sorrow. They expressed gratitude for the support and prayers from the community and emphasized their faith as a source of comfort.

Robert Jr.’s story is a poignant reminder of the complexities of addiction, mental health, and family dynamics. His journey, marked by highs and lows, reflects the challenges many face in similar circumstances.
