Maui firefighters Tuesday were called to extinguish five separate early morning fires involving abandoned cars, one of which was believed to be intentionally set.

The first alarm was called in at 2:43 a.m. in Kula on Pulehu Road, just above the Y with Omaopio Road. Firefighters found a vehicle fully involved by fire on the shoulder of the road. The cause of the fire was undetermined.

An hour later at 3:45 a.m., two more vehicle fires were reported on East Waiko Road in Waikapu. One was roughly 400 yards west of the Waiale Road intersection, and the other was about 300 yards east of the intersection.

At 3:53 a.m., a Kahului engine and tanker crew arrived at the entrance to the former Maui Scrap Metal Co. site east of the Waiale Road intersection, and found a vehicle fully engulfed in flames. The cause of the fire was undetermined.

Wailuku firefighters crew found a truck on the shoulder of Waiko Road west of the Waiale Road intersection fully engulfed by fire, which spread into the brush. Firefighters quickly brought the fire under control, but not before it burned a 50-by-200-foot area of brush and caused roughly $3,000 in damages to a nearby fence. The brush and vehicle fires were called extinguished at 4:34 a.m.

A fire investigator determined that that fire was intentionally set and originated in the bed of the truck, where a pile of car tires were believed to have been discarded.
