Mary Cosby, star of The Real Housewives of Salt Lake City, is mourning the tragic death of her 23-year-old son Robert Cosby Jr., who passed away from an opioid overdose. Robert had struggled with addiction since age 16 and despite completing rehab, continued to face legal troubles related to his substance abuse issues. His passing has sparked conversations around the accessibility of addiction treatment and the stigma surrounding relapse.

Why it matters

Robert's story is a heartbreaking example of the devastating impact of the opioid epidemic, which continues to claim lives across the country. His death highlights the urgent need for better support systems and a more compassionate approach to addressing the root causes of addiction.

The details

Police responded to Mary Cosby's Utah home on Monday evening, where they found Robert unconscious and not breathing. Narcan, a life-saving nasal spray, was administered but was ultimately not enough to save him. Two days later, Mary shared a heartbreaking statement on Instagram, writing, 'Our beloved son Robert Jr. has been called home to the Lord. Though our hearts ache, we take comfort in God's promise and in knowing he is finally at peace.' Robert's struggle with addiction began at just 16 years old, after experimenting with Xanax at a party. Despite completing rehab in December 2024, where Mary proudly shared he emerged as a 'new person,' Robert's battle with the law continued, culminating in arrests for trespassing, assault, and protective order violations.
