Cooking began prematurely before a shipment of potatoes had even left the road. Police said 57-year-old William Estabrook of Houlton knew something was wrong by the popping sound coming from his tractor trailer. He first noticed the noise around 11:30 p.m. on Thursday, June 21 as he was hauling potatoes along Interstate 95 in Etna. Estabrook told police that he pulled off to the side of the road to make a check of his rig only to see that it was on fire. From a safe distance he watched as the fire spread until the truck was destroyed. A highway closure in the area around the truck lasted about 45 minutes until emergency crews decided traffic could proceed safely again, although one lane remained closed into the next morning.
