UPDATE: Classes cancelled Monday at North MCHS as precautionary measure, the district said

UPDATE 2.8.15: Classes will be cancelled Monday, a third consecutive school-day, at North Monterey County High School, according to the district’s website.

The North Monterey County School District said it wants to give the Monterey County Sheriff’s Office more time to complete its investigation into two separate emails threatening to the shoot-up the school.

“It is still believed that the emailed threats are not from a credible source and is a hoax, however the school district takes the safety of students and staff very seriously and will continue to follow established protocols,” read a statement on the district’s website.

Sunday night, the district plans a meeting with parents at the high school to answer any questions or concerns about this situation. Sheriff Steve Bernal is expected to attend, according to the district’s website.

UPDATE 2.6.15 at 1:42 p.m.: NewsChannel 5’s Jake Reiner reports students at North Monterey County High School are being excused for the day. Parents and buses are lined up to take them home.

The Monterey County Sheriff’s Office said Friday’s second email is not identical to the one sent to North Monterey County High School on Thursday. But investigators said the email had similar threats. Deputies are still trying to figure out if it is from the same sender.

PREVIOUS STORY: North Monterey County High School was put on lockdown Thursday after a threatening email was sent to several faculty members about a mass shooting and bombs on campus.

But the Monterey County Sheriff’s Office told News Channel 5 it appears to all be a joke. The email even mentioned, the Islamic State group.

Superintendent Kari Yeater said, “at this point we’re pretty sure that it’s a hoax.”

A hoax or not, law enforcement and school leaders said they take these situations very seriously.

“We haven’t been able to validate that there’s credibility to this. But as a precautionary measure not knowing all the ins and outs we went ahead and made the decision to send our students home,” Yeater said.

Investigators said Thursday the school is safe and classes will resume like normal Friday.

If proven to be a hoax, the sender could face felony charges, deputies said.
