The Salt Lake City Police Department confirmed they responded to an overdose call on Monday evening that turned into a death investigation. Mary and her husband, Robert Cosby Sr., expressed their grief while finding solace in their faith, as the Bravo network also extended its deepest condolences.

Why it matters

His passing has left a profound impact on his family, the Bravo community, and sheds light on the ongoing challenges many face with addiction.

During season five, Robert confessed to his mother Mary, "I wanted to die at the time." In season six, Mary revealed Robert was facing legal troubles with eight charges, including a violation of a protective order involving his wife, after a relapse following a 2024 rehab stint. However, in December of that year, Mary shared that Robert had successfully completed rehab and was emerging as a new person.
