In the wake of the Valentine's Day mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, hundreds of schools have been the subject of threats in the interim.

An uptick of copycat threats after mass shootings have been documented prior to the Parkland shooting. The Educator's School Safety Network reported 369 "total incidents and threats" since February 15, and they reported an average of 50 threats per day in the week since. That's five times more than the typical 10 per day they document.

Below is a list of states where there have been multiple threats made in the last week.


Over 20 arrests have been made in more 15 instances in Indiana since the Parkland massacre. Three were made the day right after the attack, one of which included a student holding a gun and saying "don't go to school tomorrow" on Snapchat.
