Timeline of arrests and criminal cases tied to Robert Jr.
His legal troubles spanned traffic offenses, trespassing and assaults, traced in court dockets and police reports.
Key charges and pleas
- 2022: Arrested for driving under the influence. He later pleaded guilty to the DUI in exchange for dismissal of additional counts.
- September 2025: Arrested after allegedly trying to enter his then–father-in-law’s home through a dog door and assaulting a person on the property. Charges included trespass, assault and violating court orders.
- November 2025: He pleaded guilty to multiple misdemeanors related to those incidents. Several other charges were dismissed.
Court orders kept him jailed through early 2026 ahead of a scheduled sentencing.
Hit-and-run inquiry and a tense exchange with police
Police records describe an August 2022 episode in which a vehicle allegedly connected to a hit-and-run pulled into the Cosby garage. Officers said they witnessed the car enter and sought information from the household.
- According to the report, the homeowner refused to provide the driver’s name or other details.
- That encounter reportedly included accusations of racial profiling and a strained conversation between the officer and members of the Cosby household.
Mary Cosby is named in the police narrative as declining to cooperate and asking investigators to coordinate through other departments.
Private life: a secret marriage and relationship fallout
Behind closed doors, Robert Jr. married in 2022. The union later unraveled amid addiction and criminal allegations.
- He married Alexiana Arian Smokoff in August 2022, a fact Mary said she only discovered months later.
- By May 2024, an alleged domestic confrontation was reported to police months after it took place.
- Smokoff filed for divorce in November 2025 while Robert Jr. remained in custody.
Legal filings show Robert Jr. and his defense denied several of the domestic claims and sought a full hearing. They alleged the accusations were retaliatory.
Alleged domestic violence claims and the investigation
One police report details a May 2024 incident in which the alleged victim said she was attacked after flushing drugs down a toilet.
- The woman later told officers she lost consciousness and feared for her life.
- She said family members had urged her not to involve authorities at the time.
- Robert Jr., when questioned while jailed, said he could not remember everything because of drug use.
Defense attorneys have labeled some allegations as false and tied to a bitter marital split.
On-camera confession and treatment efforts
Robert Jr. made a public admission about substance use during a November 2024 episode of The Real Housewives of Salt Lake City. He discussed mixing prescription drugs with illicit substances and described dark thoughts.
By December 2024, Mary reported that her son had completed a month-long rehab stay. She later described the program as a turning point.
Legal developments in late 2025 and early 2026
After his September 2025 arrest, Robert Jr. faced a slate of charges. He pleaded guilty to a subset of those counts in November.
- Court records show he was ordered to remain in custody until sentencing.
- In February 2026, defense attorneys filed motions contesting domestic violence claims and seeking appointed counsel to handle remaining serious allegations.
Those filings accused the accuser of inventing claims in reaction to a failed marriage.
Fatal overdose response and unanswered questions
On February 23, 2026, first responders were called to the Cosby home. Dispatch audio and official notes describe a young man not breathing on arrival.
- The Salt Lake City Police Department reported officers found Robert Jr. deceased at the scene.
- Dispatch logs say at least one dose of Narcan was administered before medics arrived.
At the time of reporting, authorities had not publicly released a confirmed cause of death.
Family statements and legal representation after the death
Mary and Robert Sr. issued a written message describing their son as “called home to the Lord.” Their family attorney provided additional comment about the parents’ grief.
“Their untimely passing is hard to comprehend,” the attorney said, noting the family’s struggle to understand how a young life ended so abruptly. He praised Robert Jr.’s warmth and humor and asked for privacy as the family mourned.
