At approximately 10 p.m. University Police called the Maryville Fire Department to investigate large amounts of smoke coming from Roberta Hall.
After the fire alarm sounded residents were evacuated, UPD arrived at the scene to investigate the smoke.
University Police Chief Clarence Green said the smoke was from an elevator malfunction caused by hydraulic fluid spilling inside of the motor.
Green said there was so much smoke University Police could not find the cause of it and called in the Maryville Fire Department.
The smoke has cleared and the residents are now allowed back into the building. However, the elevator will be out of order until the parts can be replaced.
