A jewel thief left a mocking note at the scene of the crime written entirely in capital letters using a red marker. Three suspects were brought in: Mark, who had ink stains on his fingers; Nina, who wore red lipstick; and Leo, who had a red marker in his pocket. Detective Vance cleared Mark and Nina, arresting Leo. What made Leo the obvious culprit beyond just having the marker?
The note was written in marker, not pen or lipstick, but more importantly, the ink was still wet.
Leo had the exact red marker used for the note, and forensic examination showed his marker was freshly uncapped, matching the drying time of the ink.
