LAHAINA, Hawaii (AP) — As the death toll from a wildfire that razed a historic Maui town climbed to 93, authorities warned that the effort to find and identify the dead was still in its early stages. The blaze is already the deadliest U.S. wildfire in more than a century.

Crews with cadaver dogs have covered just 3% of the search area, Maui Police Chief John Pelletier said Saturday.

“We’ve got an area that we have to contain that is at least 5 square miles, and it is full of our loved ones,” he said, noting that the number of dead is likely to grow and “none of us really know the size of it yet.”

He spoke as federal emergency workers picked through the ashen moonscape left by the fire that razed the centuries-old town of Lahaina. Teams marked the ruins of homes with a bright orange “X” to indicate an initial search, and “HR” when they found human remains.

Pelletier said identifying the dead is challenging because “we pick up the remains and they fall apart.” The remains have been through “a fire that melted metal.” Only two people have been identified so far, he said.

During the search efforts, the barks of cadaver dogs alerting their handlers to potential remains echoed over the hot, colorless landscape.

“It will certainly be the worst natural disaster that Hawaii ever faced,” Gov. Josh Green said as he toured the devastation on historic Front Street. “We can only wait and support those who are living. Our focus now is to reunite people when we can and get them housing and get them health care, and then turn to rebuilding.”

At least 2,200 buildings were damaged or destroyed in West Maui, Green said, nearly all of them residential. Across the island, damage was estimated at close to $6 billion.

The Upcountry fire affected 544 structures, most of them homes, Green said.

As many as 4,500 people are in need of shelter, county officials said on Facebook, citing figures from the Federal Emergency Management Agency and the Pacific Disaster Center.

Pelletier encouraged people with missing family members to go to a family assistance center to take a DNA test.

“We need to identify your loved ones,” Pelletier said.

Those who escaped were thankful to be alive as they mourned those who didn’t make it.

Retired fire captain Geoff Bogar and his friend of 35 years, Franklin Trejos, initially stayed behind to help others in Lahaina and save Bogar’s house. But as the flames moved closer and closer Tuesday afternoon, they knew they had to flee.

Survivors witnessed a surreal landscape of flattened homes, blackened hulks of burned-out cars and ashy lots where buildings once stood as they took stock of their shattered lives in the aftermath of a fast-paced wildfire on the Hawaii island of Maui that authorities say killed at least 89 people.

Anthony Garcia assessed the devastation as he stood under Lahaina’s iconic banyan tree, now charred, and swept twisted branches into neat piles next to another heap filled with dead animals: cats, roosters and other birds killed by the smoke and flames. Somehow it made sense in a world turned upside-down.

“If I don’t do something, I’ll go nuts,” said Garcia, who lost everything he owned. “I’m losing my faith in God.”

Garcia and other residents were faced with catastrophic destruction resulting from the wildfires that tore through parts of Maui this week and were still not fully contained Friday night.

Maui County raised the number of confirmed deaths to 80 in a 9 p.m. statement Friday. Gov. Josh Green had warned the death toll would likely rise as search and rescue operations continue. Authorities set a curfew from 10 p.m. until 6 a.m. Saturday.

“The recovery’s going to be extraordinarily complicated, but we do want people to get back to their homes and just do what they can to assess safely, because it’s pretty dangerous,” Green told Hawaii News Now.

Cadaver-sniffing dogs were deployed to search for the dead, Maui County Mayor Richard Bissen Jr. said.

A new wildfire Friday evening triggered the evacuation of Kaanapali in West Maui, a community northeast of the area that burned earlier, but crews were able to extinguish the fire before 8:30 p.m., authorities said.

Attorney General Anne Lopez announced plans to conduct a comprehensive review of decision-making and standing policies impacting the response to the deadly wildfires.

“My Department is committed to understanding the decisions that were made before and during the wildfires and to sharing with the public the results of this review,” Lopez said in a statement.

The wildfires are the state’s deadliest natural disaster in decades, surpassing a 1960 tsunami that killed 61 people. An even deadlier tsunami in 1946, which killed more than 150 on the Big Island, prompted development of a territory-wide emergency system with sirens that are tested monthly.

Many fire survivors said they didn’t hear any sirens or receive a warning giving them enough time to prepare, realizing they were in danger only when they saw flames or heard explosions.

“There was no warning,” said Lynn Robinson, who lost her home.

Hawaii emergency management records do not indicate warning sirens sounded before people had to run for their lives. Officials sent alerts to mobile phones, televisions and radio stations, but widespread power and cellular outages may have limited their reach.

Fueled by a dry summer and strong winds from a passing hurricane, at least three wildfires erupted on Maui, racing through parched brush covering the island.

The most serious blaze swept into Lahaina on Tuesday and left a grid of gray rubble wedged between the blue ocean and lush green slopes. Associated Press journalists found the devastation included nearly every building on Front Street, the heart of historic Lahaina and the economic hub of Maui.

There was an eerie traffic jam of charred cars that didn’t escape the inferno as surviving roosters meandered through the ashes. Skeletal remains of buildings bowed under roofs that pancaked in the blaze. Palm trees were torched, boats in the harbor were scorched and the stench of burning lingered.

“It hit so quick, it was incredible,” Kyle Scharnhorst said as he surveyed his damaged apartment complex.

Summer and Gilles Gerling sought to salvage keepsakes from the ashes of their home. All they could find was the piggy bank Summer Gerling’s father gave her as a child, their daughter’s jade bracelet and watches they gifted each other for their wedding. Their wedding rings were gone.

They described their fear as the strong wind whipped the smoke and flames closer, but said they were happy to have made it out alive with their two children.

“Safety was the main concern. These are all material things,” Gilles Gerling said.

The wildfire is already projected to be the second-costliest disaster in Hawaii history, behind only Hurricane Iniki in 1992, according to disaster and risk modeling firm Karen Clark & Company. The fire is the deadliest in the U.S. since the 2018 Camp Fire in California, which killed at least 85 people and destroyed the town of Paradise.

The danger on Maui was well known. Maui County’s hazard mitigation plan updated in 2020 identified Lahaina and other West Maui communities as having frequent wildfires and several buildings at risk. The report also noted West Maui had the island’s second-highest rate of households without a vehicle and the highest rate of non-English speakers.

“This may limit the population’s ability to receive, understand and take expedient action during hazard events,” the plan stated.

Maui’s firefighting efforts may have been hampered by limited staff and equipment.

Bobby Lee, president of the Hawaii Firefighters Association, said there are a maximum of 65 county firefighters working at any given time with responsibility for three islands: Maui, Molokai and Lanai.

The department has about 13 fire engines and two ladder trucks, but no off-road vehicles to thoroughly attack brush fires before they reach roads or populated areas, he said.

Maui water officials warned Kula and Lahaina residents not to drink running water, which may be contaminated even after boiling, and to only take short, lukewarm showers in well-ventilated rooms to avoid possible chemical vapor exposure.

Andrew Whelton, a Purdue University engineering professor whose team assisted with the Camp Fire and Colorado’s 2021 Marshall Fire, said showering in water potentially containing hazardous waste levels of benzene is not advisable and a do-not-use order would be appropriate until analysis is complete.

Lahaina resident Lana Vierra, who filled out FEMA assistance forms Friday at a relative’s house, fled Tuesday and was eager to return, despite knowing the home where she raised five children and treasured items like baby pictures and yearbooks were gone.

“To actually stand there on your burnt grounds and get your wheels turning on how to move forward — I think it will give families that peace,” she said.

Riley Curran said he fled his Front Street home after climbing up a neighboring building to get a better look. He doubts county officials could have done more due to the speed of the onrushing flames.

“It’s not that people didn’t try to do anything,” Curran said. “The fire went from 0 to 100.”

Curran had seen horrendous wildfires growing up in California, but “I’ve never seen one eat an entire town in four hours.”
