Authorities investigate online threat against Del Norte High School

SAN DIEGO – Del Norte High School was set to remain open Thursday despite a threat made via social media, police said.

The “threat of violence” was made using the Burnbook app, according to a letter to families from Del Norte Principal Greg Mizel.

San Diego Police, Del Norte High School staff and Poway Unified School District staff do not believe it to be a credible threat, the letter stated. The school will continue with its regularly-scheduled school day Thursday, and police officers will be present on campus.

The school is working with police to identify the person responsible for the threat, according to the letter. Administrators say the person responsible will be prosecuted to the full extent of the law.

Dozens of students who spoke with Fox 5 say the Burnbook app is hurt people daily, and they wish it would simply be taken down. ” It’s just making everyone feel bad… And now this threat. I can’t pay attention to this app I have a final tomorrow,” said Mealani Quach a student from Del Norte high school.

Extra security guards will patrol the school’s campus in 4S Ranch Thursday. Several students said they were nervous about the threat.

The Poway Unified School District does not believe the threat is credible.
