Why do people make up crimes? Police now say Wisconsin college student Audrey Seiler fabricated her story about being abducted at knifepoint. The police now have evidence showing "she researched places to hide and bought rope and duct tape to make it look like an abduction.

But this is not just an attention-seeking, victimless caper. Seiler aided in the drawing of a composite sketch of the man she claimed kidnapped her.

The sketch shows a clean-shaven white man with a long chin in a stocking cap. A caption on the sketch describes the man as in his late 20s to early 30s, stocky and about 5 feet 10.

What would have happened if the police had been less dilgent in Seiler's case? What if her sketch had resulted in an arrest and she then identified the man as her kidnapper? He would have been charged, and quite possibly, wrongfully convicted.

Police have not yet determined whether Seiler will be charged with a crime.
