The tragic death of Robert Cosby Jr., son of 'Real Housewives of Salt Lake City' star Mary Cosby, has raised questions about the role of domestic violence and substance abuse in his life. The case has also brought attention to the complex dynamics between family members and the challenges of addressing violent behavior within a religious context.

Why it matters
