Firefighters were called to Mercier Grapevine Nursery in Vacaville around 3:30 Wednesday morning after getting reports that there may have been a grass fire.
When they arrived, a tractor shed behind the nursery was engulfed in flames.
As crews were putting out hot spots, they found a body among the debris.
The scene turned into a crime scene and Solano County sheriff’s detectives were called in to investigate.
The identity of the body has not been confirmed, but employees at the nursery told FOX40 that all employees have been accounted for.
Employees are being asked not to talk to one another as detectives gather statements and other evidence.
