Query: Terrific! FBI hacker chases serial killers by computer!

A great first book by AJ Holt. An FBI computer expert is banished to the southwest after she bundles a serial killer trial by using illegally obtained evidence via computer searches. She stumbles across another serial killer in New Mexico, and through a hidden bulletin board on the Internet, sets out to find other murderers who boast of their killings online. Great suspense and action... I finished the 300 plus pages in about 6 hours.... could not put it down
