LAHAINA, Hawaii – The death toll from a historic fire that roared through this Maui community rose to 93 Sunday as teams with cadaver dogs picked through the devastation, marking the remnants of homes with a bright orange "X" to signify they had been searched − and "HR" to announce where human remains had been found.

A police roadblock kept some residents out of Lahaina, largely destroyed by the deadliest U.S. wildfire in more than a century. More than 1,800 homes and structures were leveled, and hundreds of people were still missing. Maui Police Chief John Pelletier warned the search for the dead was far from over and that the death toll probably would rise.

More than 1,600 people are being housed in shelters, and possibly thousands need someplace to stay, Gov. Josh Green said. State agencies were coordinating with Maui County, the Red Cross, and the Federal Emergency Management Agency to move survivors into hotel rooms and vacation rentals, he said.

"Help is pouring in both locally and around the world as our hearts are with the people of Maui," Green said in social media posts. "'Mahalo' (thank you) to the people on the ground working to bring our loved ones home."

The death toll surpassed the fatalities in Northern California's Camp Fire in 2018. That blaze killed 85 and destroyed the town of Paradise. 

Developments:

∎Hawaiian Electric said it was working to restore power to the resort area so authorities could work with hotels and resorts to provide rooms for displaced residents.

∎At least two other fires also were burning on Maui. Damage to Lahaina and other towns in the path of fires that have swept across multiple Hawaiian islands was estimated at close to $6 billion, Green said.

What caused the Maui fire?

Much of the state was under a "red flag" fire warning when the fires started breaking out Tuesday. No official cause of the Lahaina fire has been determined, but several factors appear to have conspired to create the largest natural disaster in state history.

It's been a dry summer, and rainfall in Hawaii has declined significantly over the past 30 years. High winds from a passing Hurricane Dora fanned the flames. And climate change has been a recurring theme.

"This is the first time we’ve ever experienced a wildfire in the context of these dry conditions, global warming, and with the hurricane that is just passing us," Green said.

A class action suit was filed Saturday against Hawaiian Electric on behalf of victims and survivors. Graham LippSmith of the firm LippSmith LLP told the website Honolulu Civil Beat the suit focused on the utility's decision not to de-energize the power lines Tuesday. Hawaiian Electric spokesman Jim Kelly stressed in an email that no cause had been determined and that the company will cooperate with authorities investigating the blaze.

"Our immediate focus is on supporting emergency response efforts on Maui and restoring power for our customers and communities as quickly as possible," Kelly said.

How many people are missing in Maui?

Officials said they do not have a final count of how many people are missing, but some estimates have put the figure at 1,000 people.

Two bodies recovered from the devastation have been identified using DNA, Maui Police Chief John Pelletier said. He encouraged relatives of people still unaccounted for to visit the family assistance center in Kahului to submit DNA samples, and he expressed frustration at the difficulty in identifying remains found amid the rubble.

"We pick up the remains and they fall apart," Pelletier said. "When we find our family and our friends, the remains that we’re finding is through a fire that melted metal.”

Sen. Hirono: No excuses for tragedy

U.S. Sen. Mazie Hirono of Hawaii, speaking Sunday on CNN's State of the Union, addressed claims of residents who said they had little or no warning in the hours and minutes before the fires swept through their neighborhoods. Many locals said authorities were woefully unprepared for the disaster. The state attorney general's review of the disaster will include a look at when sirens were sounded and other actions were taken, the Democrat said.

"I am not going to make any excuses for this tragedy," Hirono said. "But we are really focused, as far as I'm concerned, on the need for rescue and, well, location of, we know, sadly, more bodies."

The state, she said, is in a period of "shock and loss." She said President Joe Biden called her to pledge his support − and was asked if Biden should declare a climate emergency.

"We very much need to acknowledge that climate change is upon us," she said, adding that "there are whole states ... where you can't even use the words climate change because they still have a head-in-the-sand attitude."

Damage to historic Lahaina 'deeply felt' by native Hawaiians

Lahaina dates back centuries and was the capital of the Kingdom of Hawaii in the early 1800s. Lahaina was "a major whaling port and fishing town in the 1800s due to its prime location on whale migration routes, calm ocean conditions and endless days of perfect sunshine," the town of about 13,000 people says on its website.

Lahaina was home to the sacred Moku‘ula palace, the center of the kingdom and the burial home to many "ali‘i" − chiefs.

"The loss of any ʻāina (land) is deeply felt by our community, but the destruction we’ve seen in Lahaina will be a scar felt for generations to come," the Council for Native Hawaiian Advancement said in a statement.

Recovery will take 'an incredible amount of time'

Hawaii has been dealing with wildfires for decades, but this time it will take "an incredible amount of time" to recover, Green said. He pledged not to let Lahaina get too expensive for locals after rebuilding.

He said the state could acquire land to use for workforce housing.

"We want Lahaina to be a part of Hawaii forever," Green said. "We don’t want it to be another example of people being priced out of paradise."

What do we know about the death count in Maui?

Officials were searching through the rubble to find answers this week. Residents were being kept away from much of the 5-square-mile area "full of our loved ones," Pelletier said.

He said the primary objective was to ensure the proper handling and identification of the dead while maintaining the safety of the community and public safety personnel. Hazards remain, such as toxic particles from smoldering embers, he added.

Pelletier said residents will not be allowed to return until it has been declared safe by hazmat teams. Anyone entering the disaster area is subject to a misdemeanor crime punishable by up to one year in jail and a $2,000 fine, he warned.

"We are asking for the public's assistance to please be patient and not rush to return," Pelletier said. "We understand that this is a trying time for everyone, and thank you for your cooperation and understanding as we work through this challenging period together."

Donations needed after Maui fire

Last week the Council for Native Hawaiian Advancement helped start the Kako‘o Maui Match Donation Fund with a goal to match up to $100,000 in donations. The goal was quickly reached and was increased to $1.5 million, which also has been met.

Donations are still being accepted and the council said 100% of proceeds will go to support relief efforts. Information on how to donate can be found here.

Maj. Gen. Kenneth Hara, of the Hawaii State Department of Defense, asked those who want to donate supplies or volunteer to do so through the Hawaii Emergency Management Agency. James Kunane Tokioka, director of the Department of Business, Economic Development and Tourism, said the governor also has asked people with vacant homes or vacation rentals to help shelter people in need.

Several shelters are open, and local organizations are collecting donations.
