LAHAINA - The death toll in Hawaii from the deadliest US wildfire in more than a century was expected to cross the 100-mark, fueling criticism that government inaction contributed to the heavy loss of life.
Officials say 93 people are known to have died, but warned the figure was likely to rise as recovery crews with cadaver dogs continued the grim task of searching burned out homes and vehicles in Lahaina.
The historic coastal town on the island of Maui was almost completely destroyed by the fast-moving inferno early Wednesday morning, with survivors saying there had been no warnings.
When asked Sunday why none of the island's sirens had been activated, Hawaii Senator Mazie Hirono said she would wait for the results of an investigation announced by the state's attorney general.
"I'm not going to make any excuses for this tragedy," Hirono, a Democrat, told CNN's "State of the Union."
"We are really focused, as far as I'm concerned, on the need for rescue, and, sadly, the location of more bodies."
More than 2,200 buildings were damaged or destroyed as the fire tore through Lahaina, according to official estimates, wreaking $5.5-billion in damage and leaving thousands homeless.
"The remains we're finding are from a fire that melted metal," said Maui Police Chief John Pelletier. "When we pick up the remains... they fall apart."
That was making identification difficult, he added, appealing for those with missing relatives to give DNA samples that might speed the process.

Pelletier said cadaver dogs still had a vast area to search in the hunt for what could still be hundreds of people unaccounted for.
"We're going as fast as we can. But just so you know, three percent -- that's what's been searched with the dogs," he said.
The wildfire is the deadliest in the United States since 1918, when 453 people died in Minnesota and Wisconsin, according to the nonprofit research group the National Fire Protection Association.
