Popular American television star Mary Cosby is grieving the unexpected loss of her 23-year-old son, Robert Cosby Jr. The Real Housewife of Salt Lake City star has long faced criticism due to her controversial marriage to her step-grandfather, Robert Cosby Sr., a church bishop, whom she married after her grandmother’s passing and divorced her first husband, Dana Harris. The couple welcomed Robert Jr. in 2002, and their lives finally felt complete.
On February 23, 2026 (ET), Robert Robert Jr., 23, was found unresponsive in Mary’s Utah home after the Salt Lake City Police Department received a 911 call and responded to a “possible overdose.” He was declared dead by the officials upon arrival. While the initial findings suggest a possible OD case, the medical examiner has not yet determined the exact cause of his death.
