What do we know about Mary Cosby’s son Robert Jr.'s death?

Sudden death, emergency response, and unresolved questions

Robert Cosby Jr., the 23‑year‑old son of Real Housewives of Salt Lake City star Mary Cosby, died after an emergency call to his family’s home. Emergency dispatch audio released around the time of his death indicates he was found unresponsive and “not breathing.” First responders administered Narcan before police arrived, evidence that responders suspected an opioid overdose or opioid involvement.

His passing follows recent legal trouble: earlier this month he had been jailed and released after facing domestic‑violence charges and other court issues. Court records also show he had previously been placed on probation with conditions that reportedly included wearing an ankle monitor and other restrictions tied to prior cases.

What we can confirm:

• He was found unresponsive during a medical emergency call to the family home.
• Narcan was administered before police reached the scene.
• He had recent legal problems, including domestic‑violence charges, a probation period, and court supervision requirements.
• Production on The Real Housewives of Salt Lake City has been paused in the wake of his death, and fellow cast members and Bravo figures have expressed condolences.

What remains unclear is the official cause of death. While the use of Narcan suggests first responders suspected an opioid overdose, no definitive public autopsy or toxicology conclusion has been released. The family has issued statements mourning him and describing their grief, while law enforcement involvement and media coverage continue as interested parties await more official findings.
