Robert Cosby Jr. (often written as Robert Crosby Jr. in some posts) – the 23‑year‑old son of “Real Housewives of Salt Lake City” star Mary Cosby – died on February 23, 2026, following what police described as an apparent overdose at his mother’s home in Salt Lake City.

Quick Scoop

What happened to Robert Cosby Jr.?

  • Police and emergency responders were dispatched to Mary Cosby’s residence on February 23 after a report that a 23‑year‑old male was “not conscious” and “not breathing.”
  • Authorities have said they responded to an overdose call, and the case has been turned over to the medical examiner for a final determination of cause of death.
  • He was pronounced dead that day, and his parents later issued statements saying their “hearts ache” and that he is “finally at peace.”

His recent legal and personal struggles

  • In the years before his death, Robert Jr. struggled with drug addiction and mental health issues, something both he and Mary discussed publicly.
  • He completed a month‑long in‑patient rehab program and at one point spoke hopefully about turning his life around, saying he wasn’t “where I want to be” but was determined to improve.
  • In 2025, he was arrested multiple times on charges including assault, criminal trespass, and violating a protective order linked to incidents involving his ex‑wife.
  • Earlier in February 2026, he was sentenced to probation with conditions such as wearing an ankle monitor, avoiding drugs and alcohol, and completing community service.
  • He had only recently been released from jail and placed on probation in early February, just weeks before his death.

Impact on “RHOSLC” and public reaction

  • Bravo and “The Real Housewives of Salt Lake City” cast members have shared condolences and paused production on Season 7 after news of his death.
  • Coverage has focused both on the tragedy of losing someone so young and on the broader issues of addiction, domestic turmoil, and mental health in the public eye.

“Our hearts ache… He is finally at peace,” Mary and Robert Cosby Sr. said in a public statement about their son.

A note on the name “Robert Crosby Jr.”

Some entertainment and forum posts appear to use “Robert Crosby Jr.” instead of “Robert Cosby Jr.,” but the widely reported story is about Mary Cosby’s son, whose legal and media references use Cosby as the surname.

If you’re looking for “latest news” and forum discussion

  • Mainstream updates: outlets like USA TODAY, PEOPLE, CTV, and entertainment sites have ongoing coverage of the investigation status and reactions from the Bravo world.
  • Forums and social threads (Reddit, Bravo fan pages, celebrity gossip boards) are actively debating:
    • How reality TV handles family trauma
    • Whether his legal troubles were over‑sensationalized
    • The line between accountability and compassion in domestic‑violence and addiction cases

Because this involves addiction and possible overdose, I’ll add: If you or someone you know is struggling with substance use, in the U.S. you can contact the SAMHSA helpline at 1‑800‑662‑HELP for confidential support and resources.

TL;DR: Robert Cosby Jr., Mary Cosby’s 23‑year‑old son, died on Feb. 23, 2026, after an apparent overdose at his mother’s home, following years of addiction and recent legal issues; the exact official cause is with the medical examiner, and “RHOSLC” halted filming in the wake of his death.
