LEE COUNTY, Fla.- Four Lee County school buses caught fire over the weekend, and now officials are calling it electrical.

Investigators with the Lee County Arson Task Force were spotted on scene at the depot off Buckingham Road on Monday morning, inspecting the charred vehicles.

Officials never said the fire was suspicious, and ultimately found it was electrical in nature.

The blaze, which started just after 4:00 a.m. on Sunday, destroyed nearly $500,000 in property.
