Dr. Dwayne Fuselier, perhaps better known as Supervisory Special Agent Fuselier, retired, was the Special Agent in charge of the FBI investigation following the Columbine School Shooting ten years ago.  Recently, a new book about this incident has been published in which Dwayne's role is extensively discussed.  (Also of interest is the fact that Dwayne's youngest son was a student at Columbine and in the school at the time of the shootings.)

Recently Dwayne, who is a specialist in hostage negotiation and criminal behavior profiling, was asked whether or not parents could be educated with respect to spotting a teenaged child's predilection for such lethal behavior as school shootings.  His response was to write the following article--you can read it here.

By the way, before becoming a Special Agent of the FBI in the early 80's, Dr. Fuselier had earned his Ph.D. in clinical psychology and had served a tour of duty as an Air Force psychologist.
