Real Housewives of Salt Lake City star Mary Cosby faces an unimaginable tragedy today. Her 23-year-old son, Robert Cosby Jr., died suddenly on February 23. Police dispatch audio reveals heartbreaking details about his final moments.

Emergency Response and Investigation
Authorities responded to a severe medical emergency at Mary Cosby’s Utah home. A 911 dispatcher reported a 23-year-old male was completely unconscious and not breathing.
First responders administered one dose of Narcan immediately. Medical professionals use this nasal spray to reverse life-threatening opioid overdoses. Unfortunately, the Salt Lake City Police Department quickly transitioned their initial overdose response into a formal death investigation.
Family and Network Statements
Mary and her husband, Robert Cosby Sr., released a joint statement recently. They expressed profound grief but found comfort in their deep faith.
Furthermore, Bravo released a public statement supporting their cherished network family member. Consequently, producers officially paused filming for the upcoming seventh season of RHOSLC.
A Public Battle with Addiction
Robert Jr. openly discussed his severe addiction struggles during recent television appearances. He admitted abusing powerful prescription drugs like Adderall and OxyContin. His dangerous addiction eventually escalated to heroin use.
Fortunately, he successfully completed a month-long rehabilitation program in December 2024. He stated he wanted to improve his life moving forward.
Recent Legal Troubles

The young man also faced significant legal hurdles recently. Police arrested him in September 2025 following a serious domestic incident. His estranged wife, Alexiana, filed for divorce shortly afterward.
He pleaded guilty to several charges and left jail on February 3. Mary previously stated these harsh legal consequences might ultimately help him heal.
