“We have someone that screamed in on the phone that they will blow the school up,” a 911 caller reported from the school at 4447 Hoover Ave. in Dayton.
The caller, who identified himself as Jim Crutcher, said all the staff and students were out of the building and that they were released on early dismissal because it was near the end of the school day.
Dayton police are investigating the threat.
