I bought this book as a source for an end-of-term project on bite-mark-analysis, and it's pros-and-cons. When I started the project, I thought bite-mark analysis was more like they showed on CSI, but I found that wasn't accurate.
Jingle Jamgle is the story of Jim Rix, who discovers that he has a cousin on Death Row, who the family swears is innocent, and he wants to know whether it's true or not. It chronicles his meeting with Ray Krone, who was dubbed the 'Snaggletooth Killer,' and put on Death Row for the murder of Kim Ancona, largely based on bite-mark evidence.
The book goes through a second trial, and then, even later, the clearing of Ray Krone via DNA evidence.
An interesting read for those interested in teeth, bite-mark analysis, or true crime. Different because it's not from the perspective of the person who did it, or someone who researched it, but a person who was actively involved in getting someone cleared after years in jail.
