Shortly after noon, El Dorado Middle School received a message that threatened the future safety of students and staff at El Dorado Middle School.

Although the message did not indicate imminent danger, EMS went into a Shelter-In-Place mode while the investigation was underway. The Shelter-In-Place policy simply means that students are not allowed to be in the hallways unsupervised. They remained in classrooms and teachers continued to teach.

"We made enough progress in identifying the source of the message that we were able to lift the Shelter-In-Place around 2:10 p.m.," stated the school district.

Students finished out the school day and dismissed at 3:00 p.m. as regularly scheduled.

An arrest was made just before 4:00 p.m.

"Student and staff safety is our number one priority and we will continue to work to maintain a safe learning environment," stated the district.
