What specific detail is included in the description of the suspect with dirty-blond hair?

The detail that identifies the suspect with dirty-blond hair specifically refers to the diamond earring on the right side of his nose. This description adds a unique characteristic that can help law enforcement officers distinguish this individual from others, as a diamond earring on the nose is relatively uncommon and specific. It effectively narrows down the identification of the suspect, making it more actionable in a law enforcement context.

While the other options provide information about accessories, height, or general hair color, they are either too general or do not distinctly contribute to the unique identification of the suspect. The mention of the diamond earring provides a clear visual cue that could aid in recognition during suspect lineups or searches, enhancing the effectiveness of the description.
