A sobering database compiled by USA TODAY, the Associated Press and Northeastern University in Boston tracks mass killings – defined as four or more dead, not including the killer. Two of the tragedies took place in Indianapolis, one apparently was not a shooting.
There were 23 mass killings in 2020, down from 45 in 2019, according to the database. James Alan Fox, the Lipman Family Professor of Criminology, Law & Public Policy at Northeastern University, said one reason for the decline might be that mass killers are often motivated by a feeling of being unfairly treated by society.
