FORT MYERS, FL--investigators are looking into what caused a fire at a Lee County school bus barn.

Four school buses sit destroyed after they mysteriously ignited in to flames early this morning and now all that is left of them are the frames.

"I will tell you that it is very seldom that buses like this catch fire," said the district's executive director of transportation, Robert Morgan.

Morgan says he isn't ruling anything out on what started this fire early Sunday morning at their east transportation lot which now looks like a crime scene.

"We have sanitized the area, kept everyone away, no one will get in to the area," Morgan said.

It's an area that houses 150 of the districts 800 school buses. The bus barn is gated and equiped with security cameras.

Six other buses that sat next to the four that caught fire were taken away to be checked for any damage.

"You are sad about the damage, but you are kind of pleased that if it does happen, it happens here and not with students on the bus," said Morgan.

Now district officials are working to get students in the classrooms Monday morning on time, but Morgan says, it will definitely have an impact.

"There is an impact in it because we bring people in on over time to make sure that the other busses are here," he said.

"Anytime you see buses like this damaged it is tax payers money," said Morgan.

Morgan says each bus costs nearly $110,000 and the district will now have to rely on older buses to pick up the slack.

"I would say that the impact it has on the students is that they will not have air conditioned buses in the morning," said Morgan.

Students will not feel an impact and will take their usual bus routes to school.
