Mary Cosby’s Son, Robert, Died In February 2026
According to a previous report from The Blast, Mary’s son, Robert, died in February 2026. He was 23.
A police report said Robert was found dead at a Utah residence after a call about a potential overdose.
“Our beloved son Robert Jr. has been called home to the Lord,” Mary said about his death. “Though our hearts ache, we take comfort in God’s promise and in knowing he is finally at peace. We are grateful for your prayers and trust in the Lord to carry us through this time of sorrow.”
Mary spoke with Robert about his drug use in previous episodes of the “Real Housewives of Salt Lake City.”
During one emotional conversation, Robert admitted to taking Xanax and other drugs to help “chill me out.”
“Then, I started doing Xanax with Acid, and then Molly with Xanax. I really like Xanax so I mix it with everything. Xanax and cocaine. You know the regular 30mg Oxys? I noticed … this was, like, a turning point for me. I was taking 10 at once, and I couldn’t even feel it,” he said.
Following the conversation, Mary was praised by Bravo figureheads, including Andy Cohen, for her handling of the intense details.
“I don’t believe in judging people. I’m just not a judger. I don’t like judging people, and I don’t like to do it. … If he’s opening up enough to tell me something this crucial, then why would I judge? I have no choice but to sit there and receive it and accept it and hope that I can help him,” she said.

“I don’t know her well, but she’s somebody who’s always been kind when I have met her, and as a mother and a fellow Housewife, I just felt I needed to be there and show up and support her,” Richards said, per The Blast. “I’m so grateful that I had the opportunity to be there and support her and experience something like that. Like I said, I will never forget that day ever in my life.”
