In the years before his tragic death, Mary Cosby's son, Robert Cosby Jr., had multiple encounters with law enforcement - including a suspected overdose inside the family home. Police reports exclusively obtained by Us Weekly reveal that officers were called to the The Real Housewives of Salt Lake City star's Salt Lake City residence at least three times over the past four years. In one incident on Valentine's Day 2023, Robert Jr. was found unconscious after overdosing and required emergency treatment from first responders.
