Police said when the crew arrived to the Carnton Plantation they saw a car outside with a man inside, but assumed someone had come to work early.
As one woman walked into an office, however, she spotted a man hiding underneath one of the desks.
The woman screamed, causing both the driver and man to flee separately. Police said the driver came back at one point to pick up the man before fleeing again.
Authorities are looking into whether or not the man was a current or former employee with access codes or a key because the alarm was set and deliberately turned off overnight.
Further details were not immediately released.
