Sixteen different schools across Colorado went on lockdown yesterday for either a fake mass shooting or bomb threat.  

The Federal Bureau of Investigation and Homeland Security are now looking into the wave of disruptive school threats across the state.

From Estes Park to Denver to Durango to Canon City, parents were on high alert as schools were the target of hoax calls, or “swatting”. Schools were put on lockdown as authorities say that threats like these are not taken lightly, especially after the number of tragic mass shootings in Colorado. 

Colorado’s Department of Emergency Management said the monitored the threats and none have been determined to be credible.
