WHITTLESEA, Australia (AP) — Disaster teams found charred bodies on roadsides and in crashed cars — grim signs of the futile attempt to flee raging wildfires fed by 60 mph winds, record heat and drought that caught even fire-savvy Australians by surprise. As the death toll rose Tuesday to 173 in Australia’s worst wildfire disaster, suspicions that some of the 400 blazes were caused by arson led police to declare crime scenes in some of the incinerated towns, Victoria police said. The fires near Melbourne in southeastern Australia destroyed more than 750 homes, left 5,000 people homeless, and burned 1,100 square miles of land.
