Mary Cosby's Son Was Slammed With Assault Charges Before His Death

Mary Cosby's son's crime slate was far from clean before he passed!

The reality star's son, Robert Cosby Jr., who died on Monday, February 23, 2026, of an alleged drug overdose, was on a strict probation order guiding his conduct since his release from jail on Tuesday, February 3, 2026.

Mary Cosby's son has battled drug addiction for a while, including his use of Xanax and cocaine, which emerged as a prominent storyline in the fifth season of "Real Housewives of Salt Lake City."

The media personality's late son was reportedly facing more legal trouble aside from his probation, as he was charged with felony domestic violence, aggravated assault, and felony domestic violence just weeks ago, from an alleged 2024 incident.

As for his most recent release, Robert was instructed to avoid using, consuming, or possessing alcohol or illegal drugs. He was also ordered to stay off locations where drugs are used, sold, or distributed outside the law.

Robert was required to wear an ankle monitor at all times after receiving a suspended sentence of 180 days and placed on probation for 24 months.

TMZ reported that in his probation requirement, he was asked not to break the law, report regularly to his probation officer, and frequently go in for routine tests for substance abuse, mental health, and anger management.

Mary and her husband, Robert Cosby Sr., issued a statement concerning their son's passing to TODAY, stating that their faith and comfort is in God's promises. They extended their gratitude to everyone who has been there for them while they carry on through this period of sorrow in their lives.

"His untimely passing is hard to comprehend, and the Cosbys are struggling to understand how someone so young and full of life could be gone so soon," the statement emphasized. Mary and Robert Sr. admitted that the late Robert Jr.'s warm spirit and kind heart will forever be remembered.

The couple has shown incredible support to Robert Jr. throughout his struggles with drug use fromthe moment they learned of his addiction. Mary and her late son even got candid about his condition in front of the "Real Housewives of Salt Lake City" cameras, where she affirmed that she would not judge nor cast him aside.

The Bravo star, during a September 2025 episode of "Real Housewives of Salt Lake City," revealed that her husband has been pivotal in keeping the family grounded while they dealt with the crushing realization of Robert Jr's addiction.

Mary revealed to her castmates that she did not have a support system at the time, and Robert Sr. proved to be very helpful by being there for her and setting her son straight. As noted by PEOPLE, in her words about what went down when Robert Jr. arrived from rehab, Mary shared:

"We had a talk with him, and Robert Sr. told him, 'We cannot babysit you. You have the tools, and you know what you need to do. So, we, like, made a pact that we would take one day at a time, and we're letting him figure it out."

Mary and Robert Sr. became parents to Robert Jr. in 2002, making him their only child, and decided to name him after his father as their purest form of love.

She reaffirmed her commitment to Robert Sr. in another interview in October, stressing that they could not go through life without him and his reassuring ways of always knowing what to say.

In November 2024, the duo let Bravo fans into their world, giving a close glimpse into Robert Jr.'s life with addiction, when it all started, and how far they have come.

As shared by The Blast, the late Robert Jr. admitted that his addiction began very slowly, with him taking half a pill of Xanax to calm his nerves and Adderall to balance out the effect of the pill.

He recalled being 16 when he began experimenting with the drugs, thinking he would only stick with the natural stuff, only for things to escalate during a visit to his friend's party, where he did Xanax with acid and Molly with Xanax, then mixing it with cocaine.

He also admitted to trying out heroin because he simply wanted to die at the time; however, the thought of his mother kept him alive. Following his arrest last year, Robert Jr.'s lawyer claimed that it was a blessing in disguise for him because it allowed him to sober up and start thinking clearly. 

Robert Jr. was arrested in November 2025 for violating a protective order by visiting his estranged wife's home. He was arrested in September 2025 after he was caught trying to enter his ex-wife's residence through a dog door and later attacking her father and a law enforcement officer.

Last October, nearly one year after the emotional 2024 episode, Mary revealed that she was shocked by Robert Jr's confession, and she found herself blaming no one but herself for his struggles.

She added that it became necessary for her to handle the situation with caution when she spoke with her late son about his behavior. Mary continued that with her patience and silence, she was filled with hope that Robert Jr. would change his ways slowly.

The reality star insisted that she decided not to judge him as that was not her character, and if her son was vulnerable enough to be honest with her, she had no choice but to "sit there, receive it and accept it."

Since his passing, Mary and her family have received an overwhelming amount of support and condolences from the Bravo family, including Andy Cohen, Crystal Kung Minkoff, Wendy Osefo, Shamea Morton, and others.

May Mary Cosby and the rest of her family find solace in the support around them in these trying times!
