A rare golden statuette was stolen from a high-security vault. The thief left behind a muddy footprint on the white marble floor. Three suspects were interrogated: a man who wore sneakers, a woman who wore high heels, and a man who wore heavy work boots. Detective Cruz looked at the footprint, which showed a distinct waffle-stamped tread, and arrested the woman in high heels. How did her footwear prove her guilt?
She claimed she never left her office, but her high heels had mud packed into the hollow heels, matching the weight distribution of the stride.
The footprint was actually left by an attachment strap she wore over her heels to frame the man with work boots, but the tread pattern uniquely matched the rubber oversoles she kept in her desk drawer.
