NBC NATIONAL NEWS — The Newtown school massacre has fueled a string of vague threats of violence at middle and high schools around the Tampa, Florida area according to Hillsborough County sheriff's deputies.
The threats - most of them on social media sites such as Facebook and Twitter - are about shootings and acts of violence in unincorporated Hillsborough County, said sheriff's Cpl. Jason Napoli. About ten schools have been named.
