Retired mailman and Vietnam veteran Thomas Leonard lived in the historic former capital of Hawaii for 44 years until this week, when a rapidly moving wildfire burned down his apartment, melted his Jeep and forced him to spend four terrifying hours hiding from the flames behind a seawall.“I’ve got nothing left,” Leonard said Thursday as he sat on an inflatable mattress outside a shelter for those who fled the blaze that decimated the town of Lahaina. “I’m a disabled vet, so now I’m a homeless vet,” he added with a small laugh.
