There have been at least 12 threats against schools across the nation since a mass shooting Wednesday at a Florida school, according to a news analysis by McClatchy.

It’s not uncommon for a mass shooting — such as the one that killed at least 17 and injured 15 more at Marjory Stoneman Douglas High School in Parkland, Florida — to inspire others.

Up to 30 percent of mass killings can be traced back to other ones from the past 13 days, according to a 2015 study from researchers at Arizona State University and Northeastern Illinois University.

The researchers wrote: “Several past studies have found that media reports of suicides and homicides appear to subsequently increase the incidence of similar events in the community, apparently due to the coverage planting the seeds of ideation in at-risk individuals to commit similar acts.”

For example, the deadly 1999 shooting at Columbine High School (13 dead and 24 injured) inspired at least 21 similar attacks and 53 plots or threats that were stopped by law enforcement, according to an analysis by Mother Jones.

A security expert told the magazine that “it’s a cult following unlike anything I’ve ever seen before.”

The Broward County Sheriff’s Office, which responded to the Parkland, Florida, shooting, sent out a message Thursday about potential copycats.

There has also been a rise in threats leveled against schools across the U.S., according to a 2015 study from the National School Safety and Security Services. The study found that there were 812 bombing and shooting threats made against schools from August to December 2014 — a 158 percent increase from the year before.

Seventy percent of the threats were made against high schools, the study found.

Here are some of the threats reported against schools since the Wednesday shootings in Florida, though not all have been determined to be copycat efforts.
