Officials as of Thursday afternoon still had not determined what caused an unusual smell in a math class that led to the evacuation of 2,300 students and staff from Stagg High School in Palos Hills on Wednesday.
The North Palos Fire Protection District was at the high school before classes began Thursday morning to test the air quality, according to Consolidated School District 230 spokeswoman Carla Erdey. Tests determined the air was safe, she said, and classes were held as scheduled.
No students or staff reported any odd smells Thursday at the school, she said.
