M. Fredric Rieders, Ph.D. is a forensic toxicologist and CEO at NMS Labs.  http://www.nmslab.com/  In this interview, Dr. Rieders provides basic information about what a forensic toxicologist does and how the work can assist law enforcement in assessing the significance of toxicological findings. 

Additionally, Dr. Rieders provides a blueprint of what can be expected in a crime laboratory in the area of quality control.  From crime scene collection to testing to interpretation of results, the integrity of the test results introduced in court are dependent, in part, on the integrity of the procedures implemented by the crime lab.  Dr. Rieders gives us an insider's view of the inner workings of forensic crime labs.
