LAHAINA, Hawaii (AP) 鈥 Authorities in Hawaii pleaded with relatives of those missing after the deadliest U.S. wildfire in more than a century to come forward and give DNA samples, saying the low number provided so far threatens to hinder efforts to identify any remains discovered in the ashes.

Some 1,000 to 1,100 names remain on the FBI's tentative, unconfirmed list of people unaccounted for after wildfires destroyed the historic seaside community of Lahaina on Maui. But the family assistance center so far has collected DNA from just 104 families, said Julie French, who is helping lead efforts to identify remains by DNA analysis.

Maui Prosecuting Attorney Andrew Martin, who is running the center, said that the number of family members coming in to provide DNA samples is 鈥渁 lot lower" than in other major disasters around the country, though it wasn鈥檛 immediately clear why.

鈥淭hat鈥檚 our concern, that鈥檚 why I鈥檓 here today, that鈥檚 why I鈥檓 asking for this help,鈥 he said.

Martin and French sought to reassure people that any samples would be used only to help identify fire victims and would not be entered into any law enforcement databases or used for any other purpose. People will not be not asked about their , they said.

鈥淲hat we want to do 鈥 all we want to do 鈥 is help people locate and identify their unaccounted-for loved ones,鈥 Martin said.

Compounding the collection problems are scams that have popped up, county officials said Wednesday. The family assistance center received reports about people receiving calls from individuals or organizations claiming to be with 鈥淒NA Services,鈥 the county said in a statement. The center's staff members are not calling community members to request DNA samples, it said.

Two weeks after the flames tore through Lahaina, officials are facing huge challenges to determine how many people who remain unaccounted for perished and how many made it to safety but haven't checked in.

Something similar happened after a wildfire in 2018 that killed 85 people and destroyed the town of Paradise, California. Authorities in Butte County, home to Paradise, ultimately published a list of the missing in the local newspaper, who had made it out alive but were listed as missing. Within a month, the list dropped from 1,300 names to .

Hawaii officials have expressed concern that by releasing a list of the missing, they would also be identifying some people who have died. In an email Tuesday, the State Joint Information Center called it "a standard held by all law enforcement and first responders here in Hawaii, out of compassion and courtesy for the families, to withhold the names until the families can be contacted.鈥

There have been 115 confirmed dead, according to Maui police. All single-story, residential properties in the disaster area had been searched, and teams were transitioning to searching multi-story residential and commercial properties, Maui County officials said in an update late Monday.

Police Chief John Pelletier said Tuesday that his team faces difficulties in coming up with a solid list of the missing. In some cases people only provided partial names, and in other cases names might be duplicated. There was 鈥渘o secrecy, no hiding things,鈥 he added.

鈥淲e want to get a verified list. The 1,100 names right now, we know that there鈥檚 a margin of that that some of them have first names only and there鈥檚 no contact number back. So there was a, 鈥楯ohn鈥檚 missing,鈥 and when we try to call back who said that, no one is answering,鈥 he said. 鈥淎nd so we鈥檙e trying to scrub this to make it as accurate as we can.鈥

Pelletier urged people to provide DNA and file a police report with as much information as possible if they have relatives unaccounted for.

"If you feel you鈥檝e got a family member that鈥檚 unaccounted for, give the DNA,鈥 he said. 鈥淒o the report. Let鈥檚 figure this out. A name with no callback doesn鈥檛 help anybody.鈥

One whose name was on the list was Roseanna Samartano, a resident of Lahaina, who didn鈥檛 know anyone was looking for her until an FBI agent phoned her a few days ago.

鈥淚 was shocked. Why is the FBI calling me?鈥 the 77-year-old retiree said. 鈥淏ut then he came out with it right away, and then I kind of calmed down.鈥

It turned out a friend had reported her missing because he'd been unable to get in touch despite calling, texting and emailing. Her neighborhood of Kahana 鈥 which didn鈥檛 burn 鈥 had no power, cellphone service or internet in the days after the fires.

Clifford Abihai came to Maui from California after getting nowhere finding answers about his grandmother, Louise Abihai, 98, by phone. He has been just as frustrated on the ground in Maui.

"I just want confirmation,鈥 he said last week. 鈥淣ot knowing what happened, not knowing if she escaped, not knowing if she鈥檚 not there. That鈥檚 the hard thing.鈥

As of Tuesday, he said, he still had learned nothing further. He did provide a DNA sample, he said.

Abihai's grandmother lived at Hale Mahaolu Eono, a senior living facility where another member of his extended family, Virginia Dofa, lived. Authorities as one who perished. Abihai described Dofa and Louise Abihai as best friends.

He said his grandmother was mobile and could walk a mile a day, but it was often hard to reach her because she'd frequently turn off her cellphone to save battery power.

Confirming whether those who are unaccounted for are deceased . Fire experts say it鈥檚 possible some bodies were cremated by the intense heat, potentially leaving no bones left to identify through DNA tests. Three-quarters of the remains tested for DNA so far have yielded usable results, French said.

People who lived through other tragedies and never learned of their loved ones' fate are also following the news and hurting for the victims and their families. Nearly 22 years later, for example, almost 1,100 victims of the 9/11 terror attacks, which killed nearly 3,000, have no identified remains.

Joseph Giaccone鈥檚 family initially was desperate for any physical trace of the 43-year-old finance executive, who worked in the World Trade Center's North Tower, brother James Giaccone recalled. But over time, he started focusing instead on memories of the flourishing man his brother was.

If his remains were identified and given to the family now, 鈥渋t would just reinforce the horror that his person endured that day, and it would open wounds that I don鈥檛 think I want to open,鈥 Giaccone said Monday as he visited the 9/11 memorial in New York.
