Legal history: arrests, DUI and time in custody

Context compiled from multiple reports shows Robert had a string of legal issues in recent years. He was arrested in Utah in September on allegations that included trespassing and assault. He was also arrested in November for allegedly violating a restraining order put in place by Alexiana Smokoff’s family. Earlier, he was arrested for DUI in 2022; police said he did not have a license and disobeyed traffic laws. He pleaded guilty to the DUI and was released from prison in February.

Marriage, divorce filing and reality‑show storylines

Robert’s death comes four months after his estranged wife, Alexiana Smokoff, filed for divorce following three years of marriage. The former couple reportedly married in a Utah courthouse in August 2022, a secret union that unfolded on camera during Season 4 of the reality series in which the family has appeared. Their alleged drug use was later featured as a storyline during Season 6, which was filmed in early 2025.

On the show, Robert described his recovery after a 30-day rehab stint, telling his mother, "I’m not in that dark place, but, like, it’s still there, if that makes sense, " and saying he was "at a standstill. " Later in that season, his relapse was revealed following the November arrest for allegedly violating the restraining order. Mary addressed that episode directly, saying, "[Her family] filed a restraining order against him, and he went back anyway, thinking that she want[ed] him to come back and save her. I don’t know where he’s getting that from … delusional. "

Public reactions and earlier coverage

News of Robert’s death was first announced in an earlier report. A public figure tied to the television franchise, Andy Cohen, posted Wednesday: "Devastatingly sad news out of SLC. 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. "

Mary’s representative did not immediately respond to a request for comment on the developing investigation. Many details about the cause of death and the full timeline remain unclear in the provided context as authorities continue their inquiry.
