A Mother's Testimony Before a Family Tragedy

Newly surfaced police reports from Salt Lake City reveal that Mary Cosby, known for her role on The Real Housewives of Salt Lake City, sat for an interview with investigators on January 9, 2026. This meeting occurred just six weeks before her son, Robert Cosby Jr., died in February. According to the documents, officers were probing a report filed by Robert's then-wife, Alexiana Smokoff, who alleged a violent encounter had taken place at Cosby's residence in May 2024. The timing of the police interview suggests that authorities were actively building a case against the younger Cosby during the final months of his life.

The Allegations of a Violent Domestic Dispute

The investigation was initiated after Smokoff contacted law enforcement in late 2023 to report an incident involving alleged strangulation. According to the police report, Smokoff claimed that Robert became enraged after she disposed of his narcotics. She told officers that he grabbed her by the throat, causing her to lose consciousness, and also accused him of spitting on her during the altercation. These details emerged as part of a delayed report, as Smokoff noted she was motivated by a desire to document the pattern of behavior following Robert’s subsequent incarceration on unrelated matters.

Conflicting Accounts of Family Dynamics

During her session with investigators, Mary Cosby defended her son's character and denied any knowledge of physical violence. According to Salt Lake City Police, Cosby stated that while the couple engaged in verbal arguments, she never witnessed her son strike or injure his wife. She emphasized to officers that she did not raise him to be a violent person and maintained that his temperament was generally non-aggressive. However, she did recount one specific instance where Robert and another individual sustained injuries after jumping from a balcony while under the influence of illicit substances.
