Extra Police Officers At Sudbury School After Threat Involving Gun

SUDBURY (CBS) – Extra police officers were at Curtis Middle School in Sudbury Thursday, a day after a serious threat was reported.

Investigators said a student alerted them to the threat "involving a firearm" after seeing it posted on Snapchat.

"A student actually reported it to an administrator at the middle school last evening. The administrator then contacted me and the police," said Sudbury Public Schools Superintendent Dr. Anne Wilson.

They determined overnight the student had no credible access to guns.

Police Chief Scott Nix said they have not determined yet if charges will be filed, but they have identified a suspect who could face criminal charges and/or discipline from the school.

"We took it credibly but there is no current existing threat, hence why we went with school going in session," Nix told reporters.

Parents got an email around 10 p.m. Wednesday alerting them to the investigation, but no additional details were given about the nature of the threat, until police issued a news release Thursday morning, announcing that the school would be open for classes as scheduled.

There was a heavy police presence all day long as a precaution.

"If there is anything positive that can be said about the situation, the fact that a student did report it is exactly what we go for and exactly what we want," Wilson said.

"It makes us all live in a state of constant anxiety," Sudbury resident Barbara Keiler told reporters outside the school Thursday. "My heart goes out to all the parents of these kids too.  I'm sure they're feeling the very same thing."
