Mary Cosby, known for her role on “Real Housewives of Salt Lake City,” recently shared her heart-wrenching concerns about her son’s well-being just months before his tragic death.

Robert Cosby Jr., passed away at the age of 23 on Monday. While the official cause of death has yet to be disclosed, police initially responded to reports of a ‘possible overdose.’ The investigation is ongoing and has been classified as a death investigation.

The Salt Lake City police confirmed to TMZ that officers were dispatched Monday night to address a ‘full arrest/medical emergency’ involving the young man. Further details have not been made public at this time.

Robert’s life had been tumultuous, marked by legal troubles and alleged substance abuse issues. During the second part of the “RHOSLC” Season 6 reunion, which aired on January 20, Mary Cosby became emotional while discussing her only child.

At the time of filming, Robert was incarcerated at the Salt Lake County Metro Jail following his November arrest for allegedly breaching a pretrial protective order against his ex-wife, Alexiana Smokoff.

Mary shared with the cast, “I’m not worried about him,” expressing relief in knowing he was in a place where he couldn’t use drugs. She added, “I’d rather him be there than dead, you know?”

She went on to say she felt she had no choice but to let him face the consequences of his actions.

‘At some point, I have to step back so that he can learn and he can make his own decisions, and unfortunately, he’s learning the hard way. But I’m OK with it,’ she said.

‘It’s just, you don’t want to see your kid suffer, but I know it’s good,’ Mary explained.

Robert Jr. was released from jail earlier this month after serving two months behind bars. 

He had been ordered to serve 99 days but received credit for time served.

Bravo confirmed the tragic news in a statement provided to the Daily Mail.

‘We are heartbroken to learn of the passing of Mary’s beloved son, Robert Jr. Mary is a cherished member of our family, and our thoughts, love, and deepest condolences are with her and her loved ones during this incredibly difficult time.’ 

A separate statement was also shared on behalf of Mary Cosby and her husband, Robert Sr. Cosby.

‘I’m not worried about him,’ Mary explained to the cast, admitting it gave her comfort knowing he was somewhere he wasn’t using drugs, adding, ‘And I’d rather him be there than dead, you know?’

‘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. We are grateful for your prayers and trust in the Lord to carry us through this time of sorrow.’

Mary Cosby has appeared on The Real Housewives of Salt Lake City since its debut, with her family life occasionally featured on the show.

Following the news, Andy Cohen took to Threads to react to the heartbreaking news. 

‘Devastatingly sad news out of SLC,’ Cohen wrote. ‘This is every parent’s worst nightmare. My heart is broken for Mary, and I am sending all my love to her and Robert Sr.’ 

Robert’s death comes just weeks after he was released from Salt Lake County Metro Jail after serving two months behind bars. 

At this time, his attorney Clayton Simms told People that Robert ‘expresses deep regret regarding his prior actions and acknowledges that his past behavior demonstrates poor judgment.’ 

Three days after his release, Robert’s mom shared a photo of him, alongside the cryptic message, ‘Thank you all for your prayers. Love you.’ 

At the time, members of the Real Housewives franchise expressed their support in the comments section.

At the time the episode was filmed, Robert was being held at Salt Lake County Metro Jail following a November arrest for allegedly violating a pretrial protective order against his now ex-wife, Alexiana Smokoff

‘Lots of prayers for you and Robert, Mary,’ The Real Housewives of Beverly Hills’ Sutton Stracke wrote. 

Dolores Catania, from The Real Housewives of New Jersey, commented: ‘God bless Robert.’ 

Her Real Housewives of Salt Lake City costar Heather Gay simply sent her ‘love.’ 

In November, his wife, Alexiana Smokoff, filed for divorce. 

Viewers of The Real Housewives of Salt Lake City saw Robert appear on the Bravo series several times over the years. 

During season four, Mary Cosby addressed learning that her son had secretly married Alexiana without her knowledge. 

The wedding reportedly took place in August 2022 at a Utah courthouse.

Robert and Alexiana’s alleged struggles with substance use were also featured as part of Mary’s storyline on the show.

Robert had a history of legal issues. 

He was arrested in Utah in September on multiple alleged charges, including trespassing and assault. 

He was previously arrested in 2022 for driving under the influence, at which time police said he did not have a valid license and failed to follow traffic laws.

He later pleaded guilty to the DUI charge. 

During part 2 of The Real Housewives of Salt Lake City season 6 reunion, which aired in January, Mary spoke about her son’s arrest and time in jail. 

‘I know he’s somewhere where he’s not using,’ she said. ‘Unfortunately he’s learning the hard way, but I’m okay with it.’

Still, she said, as a mother, ‘you don’t wanna see your kid suffer, but I know it’s good, and I’d rather him be there than dead.’
