There was this movie: A Guy Thing
The woman's fiance is attacked by her former boyfriend, who is a cop.
The woman, unaware of this, calls the police. But her fiance is afraid to give a description of the guy, so he describes a fictional assailant with weird facial features and ginger-dreadlocks. The police catches a man fitting the exact same description.
This case is turning into something of that sort.
A crime committed by a perp with a very inconsistent, hard to find criminal behavior pattern.
