Many mass killings are rooted in some sort of grievance — real or imagined unfair treatment — a West Virginia University expert said in the aftermath of the Texas elementary school shootings that left more than 20 dead.
Jeff Daniels, a professor of counseling, helped develop a model that focuses on detectable behaviors of school and workplace violence perpetrators based on research in an upcoming book. Daniels, who studies school violence, hostage crises and police ambushes, said the model aims to identify people “going down what we call the fatal grievance pathway.”
