After beginning winter break early in response to written threats, Pacific Cascade Middle School will reopen as normal Monday, Jan. 5.

The school day will be delayed one hour to accommodate a 7:40-8:10 a.m. parent meeting regarding the status of a police investigation into the mysterious letter.

On Dec. 17, as buses were already collecting students to begin the school day, Pacific Cascade employees discovered a typewritten letter outside a classroom. The letter contained threats to four staff members, suggested the author had access to a gun and promised violence at lunch or the school’s scheduled pre-break Winter Assembly.

Administrators immediately shut the school down, redirected arriving buses and contacted law enforcement.

As an investigation went forward the next two school days without any leads, administrators kept the school shut down.

But with the dates of promised violence past, the campus will return from winter break normally pending new information.

Principal Dana Bailey wrote in a letter to school families that parents will be welcome to stay as long as they like after the meeting to “be extra eyes and ears.”

Any new information in the investigation will be announced via email blast, the Issaquah School District website and social media, Bailey wrote.
