Real Housewives of Salt Lake City star Mary Cosby's son, Robert Cosby Jr., faced two felony assault charges weeks before his death. Us Weekly can confirm that Robert Jr. was charged with one count of aggravated assault and one count of assault in connection with a domestic violence incident that took place in May 2024. A warrant for Robert Jr.'s arrest was issued on February 5. The alleged victim is identified in court documents obtained by Us on Thursday, February 26, by the initials A.S. (While no name was given in the filing, Robert Jr. was married to a woman named Alexiana Smokoff.) Mary Cosby Charles Sykes/Bravo A.S. alleged that Robert Jr. struck her in the face and head, and "kicked her in the stomach," after she "flushed his drugs down the toilet." A.S. further claimed that Robert Jr. "grabbed her by the throat" and "strangled her for 10 seconds," according to the documents. A.S. provided authorities with photos of her alleged injuries, which showed her with "red and swollen" eyes, a "red mark" on her neck and "a lump" below her left eyebrow. Robert Jr.'s ex-wife filed for divorce in November 2025 after nearly three years of marriage. The following month, Robert Jr. pleaded guilty to trespassing and assault following several incidents involving Smokoff and her father. He was also accused of violating a protective order. Mary Cosby's Son Robert Jr.'s Ups and Downs on 'RHOSLC' Before Death at 23 Robert Jr.'s divorce from Smokoff was finalized last month, while he was still incarcerated. Robert Jr. was released from jail earlier this month. "I'm back :)," he captioned his return to Instagram on February 6. Us confirmed on Wednesday, February 25, that Robert Jr. died at age 23 following a suspected overdose in his parents' Utah home. "Our beloved son Robert Jr. has been called home to the Lord," Mary shared in a statement to Us. "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." Robert Jr.'s addiction battle was showcased on RHOSLC throughout the past two seasons. Mary received praise from viewers for her honesty about his struggles. Bravo Robert Jr. admitted to his life feeling like "chicken unseasoned" during a November 2024 episode of the Bravo show. (Mary confirmed the following month that Robert Jr. had completed a month-long stay in rehab.) "When I get high, it's like adding seasoning to it," he said on camera. "At first, I was like, 'I'm going to just stick to natural stuff.' Then, I went to a party, and someone gave me Xanax. I started buying it. Then, I started doing Xanax with acid and then molly with Xanax. I really like Xanax, so I mix it with everything." Mary spoke candidly about her son's arrest and jail time during the RHOSLC season 6 reunion last month. "I'm not worried about him," she said. "I know he's somewhere where he's not using. 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."
