As many as four Elkhart school buses have been destroyed in a fire at Elkhart Central High School that police say was set by vandals. Firecrews were called to the scene just after midnight, Tuesday morning, to find the buses ablaze. The Elkhart Truth reports they had just been used, hours earlier, to transport students to some sporting events. It's believed the fire was started on one bus, then spread to the others. Two of the buses were outfitted with wheelchair lifts for special needs students.Elkhart Community Schools is reviewing surveillance tapes. Elkhart Police detectives are also asking for anyone who might have seen something suspicious to give them a call.
