CNN  — 

The death toll in the Maui wildfires has risen to 106, Maui County officials said Tuesday, a week after the flames started sweeping through parts of the Hawaiian island.

The update on the death toll – up from 99 a day before – came as authorities said only five of the dead had been identified. County officials released two names and said the three others would be announced after their relatives are notified.

Authorities had gone through about a third of the search area as of Tuesday; the county put the figure at 32% while Hawaii Gov. Josh Green told CNN Tuesday it was 27%.

With so much still to search, the death toll still could rise significantly, Green has said.

“Over the course of the next several weeks, we’ll be able to confirm who passed away. But it’s gonna be very difficult going,” the governor told CNN’s Kaitlan Collins on Tuesday.

Many deaths happened on a highway down by the ocean in western Maui, he said.

“I think many of the fatalities that we’ll ultimately discover, a higher percentage will be from there,” he said. “But now that we’re going to the houses, we are not sure what we will see. We’re hopeful and praying that it’s not large, large numbers.”

It’s unclear how many people are unaccounted for, in part because of communication gaps, Green said Monday. “A lot of people had to run and left all they had behind. They don’t have their phones – the phones are incinerated,” he said.

A portable morgue unit has arrived in Hawaii and will help authorities identify and process remains with equipment such as examination tables, X-ray units and laboratory equipment, Jonathan Greene, deputy assistant secretary of the US Department of Health and Human Services, said Tuesday.

Maui Police Chief John Pelletier said in a Monday news conference that he hopes searchers will have covered 85% to 90% by the weekend.

The hall of the historic Waiola Church and the nearby Lahaina Hongwanji Mission are engulfed in flames in Lahaina on August 8.

“We started with one dog. We are at 20,” Pelletier said Monday. “We can only move as fast as we can, but we got the right amount of workers and teams doing it.”

Crews are going through what used to be homes, business and historic landmarks burned to the ground after wind-whipped wildfires began spreading erratically August 8, suddenly engulfing homes, forcing harrowing escapes and likely displacing thousands especially in western Maui’s Lahaina area.

There were 185 people on search-and-recovery teams, the governor said Tuesday.

“Nothing can prepare you for what I saw during my time here, and nothing can prepare them for the emotional toll of the impact that this severe event has taken on them,” FEMA Administrator Deanne Criswell told reporters Monday.

The Maui wildfires are the deadliest in the US in more than 100 years, according to the National Fire Protection Association.

Two people go through a burned-out house in Lahaina, Hawaii on Sunday.

As firefighting and search efforts continue, here’s the latest on what’s happening on Maui:

• Key road to open: The Lahaina Bypass in West Maui will be open to the public from 6 a.m. to 10 p.m., beginning Wednesday. Residents, emergency responders and employees of local business can also use the roads 24 hours a day, the governor said. The bypass is a main road, about a quarter-mile inland from the shore.

• Burn victims treated: Nine people injured in the wildfires have been admitted to a specialized burn unit in Honolulu, the only burn unit in the state and the Pacific Region, according to Straub Medical Center.

• President Biden touts future visit: The president told reporters Tuesday he will visit Hawaii with the first lady “as soon as we can.” Biden pledged the state would have “every asset they need” for ongoing recovery and rebuilding efforts. The president mourned the loss of life and “generations of native Hawaiian history turned into ruin” while reiterating a robust federal response, even as some on Maui have voiced frustration at the slow pace of aid.

• Calls to provide DNA: Those with missing family members have been urged to contact authorities to provide DNA samples, which would help in the identification process. Only three of those killed could be identified through fingerprints, Pelletier said, stressing the need for the DNA swabs.

• County names two victims: Robert Dyckman, 74, and Buddy Jantoc, 79, both of Lahaina, were killed, Maui County officials said Tuesday. Names of other victims have been released by families.

• Homes lost: More than 2,200 structures have been destroyed or damaged by the fires – about 86% of them residential, Green has said.

• Rooms for displaced residents: There are 473 listings in the state with the Hawaii Fire Relief Housing Program, the governor said in a video statement Tuesday. That is in addition to 500 hotel rooms and more than 1,000 rooms or houses that are being covered by government agencies, Green said.

• Power coming back: The fires wiped out both power and communications for thousands. Hawaiian Electric announced it had restored power to about 80% of its customers on Maui. On Monday, crews restored power to schools and county facilities in some areas of Lahaina, the utility said Tuesday. “The focus continues to be safely restoring areas that provide essential public services as well as facilities serving first responders and the emergency response efforts,” officials said.

• Lawsuit over power lines: Hawaiian Electric is facing a lawsuit claiming power lines blown over by high winds helped to cause the destructive Lahaina wildfire, though an official cause has not yet been determined.

• Coast Guard shifts focus: The US Coast Guard in Maui is moving from search and rescue mode to containing potentially hazardous materials in the ocean left behind by the fires. Sonar technology was brought in and a 100-foot boom placed at the mouth of the Lahaina Harbor, the service said.

Stories emerge of those lost in fires

Franklin "Frankie" Trejos and Carole Hartley were identified by their families as victims of the Maui wildfires.

Families of two victims told CNN their loved ones died while trying to escape the Lahaina fire.

Maui resident Carole Hartley, 60, and her partner, Charles Paxton, were trying to evacuate when the smoke from the fire overwhelmed the couple and they got separated, her sister Donna Gardner Hartley told CNN.

Winds were vicious and they couldn’t see through dark smoke that “felt like a tornado,” Gardner Hartley recalled Charles telling her.

“They kept calling each other’s name,” Gardner Hartley said in a Facebook post. “He was screaming, ‘Run, run, run, Carole run.’ He eventually could not hear her anymore.”

Paxton, who was found by his friends, organized a search for Hartley after he was treated for his injuries, the sister said.

Hartley’s remains eventually were found on the couple’s property over the weekend, Gardner Hartley told CNN.

Hartley was described by her sister as a free spirit who “always looked for the good in people and always helped others.”

Franklin “Frankie” Trejos, 68, also died trying to escape the Lahaina fire, his niece Kika Perez Grant told CNN.

The family got a call from Trejos’ roommate letting them know that the island was on fire and that he wasn’t sure if Trejos had made it out alive, Perez Grant said.

“We kept hope alive, but then his roommate called us again a few hours later to tell us he had found Uncle Frankie’s remains,” Perez Grant said.

Trejos and his roommate tried to save their property at first, but then decided to leave in their own cars when they realized it was impossible, Perez Grant said.

The roommate later found Trejos’ car a few blocks from the house, with Trejos’ remains on top of the roommate’s dog, which also died, Perez Grant said.

Trejos, a native of Costa Rica who had moved to the United States at a young age, lived in Lahaina for the last 30 years, according to his niece.

“Uncle Frankie was a kind man, a nature lover, an animal lover and he loved his friends and his families with this whole heart,” Perez Grant said. “He loved adventure and was a free spirit.”

Questions over siren systems and fire hydrants

As the fires quickly advanced on the historic town of Lahaina last week, first responders encountered weak water pressure and fire hydrants running dry, several firefighters told the New York Times.

“There was just no water in the hydrants,” Keahi Ho, one of the firefighters working in Lahaina, told the paper.

Another firefighter, unnamed by the paper because he was not authorized to discuss the operation, said his truck connected to a hydrant but the water pressure was too weak to be of use, and the flames spread beyond firefighters’ ability to contain them.

CNN sought comment and information from the Maui County Department of Water Supply.

Asked about reports that firefighters didn’t have enough water to tackle the blazes on August 8, the governor told reporters in a news conference Monday: “One thing that people need to understand, especially from far away, is there’s been a great deal of water conflict on Maui for many years.”

“We have a difficult time on Maui. In other rural areas, getting enough water for houses, for our people, for any response,” Green said.

West Maui residents have described the fires jumping across highways and showing up in their yards or their engulfing homes without warning, forcing them to run for their lives.

Hawaii’s network of about 400 alarms, meant to alert residents to tsunamis and other natural disasters, did not activate as the fire spread August 8, Hawaii Emergency Management Agency spokesperson Adam Weintraub.

Although the emergency response is still being reviewed, authorities believe the sirens were “essentially immobilized” by the extreme heat, Green told CNN on Monday.

The governor told CNN on Tuesday that some of the sirens were broken, and that is part of an ongoing investigation.

Green said he asked the state’s attorney general “to do a full review of everything: decisions, policies, policies on water, and then of course the sirens.”

“A lot of people would have, I am sure, at least been alerted more quickly, and that is important,” Green said.
