“We do have extreme concerns that because of the temperature of the fire, the remains of those who have died, in some cases, may be impossible to recover meaningfully. So there are going to be people that are lost forever,” Green said.

A Maui official has said children may make up a large portion of the missing. Green told Brennan that could be true.

“That is possible. And that’s-that’s what we’re sharing here internally, that it’s possible that there will be many children,” Green said, “This is the largest catastrophe and disaster that’s ever hit Maui, probably that’s ever hit Hawaii outside of wartime events.”

As of Sunday, the death toll in Maui was more than 100.
