Extracting Evil: Dr. Beckett Campbell, Medical Examiner, Book 5 (Unabridged‪)‬

Spolier alert: 

Beckett's dead, and Suzan's been institutionalized. And now, with the two of them out of the way, the twisted DNR Group is free to pursue their brutal agenda without opposition. What they didn't count on, however, is someone unexpected stepping up and trying to put a stop to them. I mean, there are more than seven billion people on this planet...somebody has to step up, don't they? 

Don't they?
