“We have wrapped up almost completely the search and recovery mission and moving into the next phase,” Darryl Oliveira, the interim administrator of the Maui Emergency Management Agency, said at a news conference.

The next phase would be hazardous waste removal conducted by the U.S. Environmental Protection Agency, he said.

Maui Police Chief John Pelletier said urban search and rescue teams have “completed 100% of their area” but some search activity continues in the ocean off Lahaina.

The FBI is searching 200 yards out, along a four-mile stretch of coastline, but no human remains have been found, he said. There are 110 missing persons reports filed with Maui police, and more than 50 of those remain open cases that are still actively being worked, he said.

Although the initial land search is complete, authorities may also use details from the missing person reports to go over areas again, he added.

“They say, ‘My loved one was here’ and this may be a data point and we can continue,” Pelletier said. “In case there was a chance that something needs to be further looked at, we’ve got archeologists and we’re gonna make sure that we can do that so, again, we do this the right way.”

He asked for “trust and patience” as officials continue to identify remains and go through lists of the missing.

So far, authorities have identified and notified the loved ones of 45 of those killed. They have collected DNA from 120 people to identify the dead and continue to see more samples.
