Plot summary
A behavioral profile is helpful in a murder investigation, but it's not a road map to the killer. One such profile caused the Baton Rouge Police Department to search for the wrong man.

They might not have made an arrest, had it not been for a DNA picture of the suspect, painted by a molecular biologist.
