The Iowa killings were the sixth family mass killing so far this year, said James Alan Fox, a criminologist at Northeastern University.

The Iowa killings were the sixth family mass killing so far this year, said James Alan Fox, a criminologist at Northeastern University.

This is the largest such case in at least 20 years, according to a review of a mass killings database by USA TODAY, the Associated Press and Northeastern University research professor of criminology James Alan Fox.

James Alan Fox, a professor of criminology, law and public policy at Northeastern University in Boston, oversees the database and continues to add information drawn from media reports, FBI data, arrest records, medical examiners’ reports, prison records and other court documents.

“When crime goes up and spikes upward, it tends to drop following that,” James Alan Fox, a criminologist at Northeastern University, told GBH’s Adam Reilly. “And when you have particularly low points, like we did last year, the tendency is to go up a little bit.”

The scope and horror of American gun violence can create the impression of an intractable problem. But that impression runs counter to the data, according to James Alan Fox, a criminologist at Northeastern University.

“This is not a victory lap for gun reform—it’s a return to a more typical level,” said James Alan Fox, a research professor of criminology, law, and public policy at Northeastern who oversees the database, in an interview with Newsweek.

“Sir Isaac Newton never studied crime, but he says ‘What goes up must come down,’” said James Alan Fox, a criminologist at Northeastern University. 

The mass killings — defined as incidents in which four or more people are killed in a 24-hour period, not including the killer — are tracked in the database maintained by The Associated Press and USA Today in partnership with Northeastern University. Fox, who manages the database, says mass killings were down about 24% this year compared […]
