A crowd of students cleared out of McKinney Hall Saturday night, while at least one police car, one ambulance and three fire engines flashed their lights along Fourth Street.

The students responded to a fire alarm, triggered by a cooking mishap, said firefighter James Calvert.

The Charleston Fire Department received the call at 10:28 p.m. and left the scene at 12:06 a.m. They blamed the alarm on “burnt popcorn.”
