LEBANON, Mo. - A driver going by the Fidelity Building on Springfield Road saw the fire just before 11 p.m. Tuesday.
A captain with the Lebanon Fire Department said firefighters had to bust through the garage door to attack the fire. About three-quarters of the inside of the business is damaged.
No one was inside the building when the fire started.
Investigators will look into the cause, including the possibility that lightning could have started the fire.
