An emergency official who defended a decision to not sound outdoor alert sirens on Maui as a ferocious fire raged has resigned.

Maui Emergency Management Agency Administrator Herman Andaya had said this week that he had no regrets about not deploying the system because he feared it could have caused people to go “mauka,” a Hawaiian term that can mean toward the mountains or inland.

“If that was the case, then they would have gone into the fire,” Andaya explained. He stepped down Thursday, a day later.

The decision to not use the sirens, coupled with water shortages that hampered firefighters and an escape route clogged with vehicles that were overrun by flames, has brought intense criticism from many residents following the deadliest wildfire in the U.S. in more than a century.

With the death toll at 111, the search for the missing moved beyond the devastated town of Lahaina to other communities that were destroyed. Teams had covered about 58% of the Lahaina area and the fire was 90% contained as of Thursday night, Maui County officials said.

Six forensic anthropologists with the Department of Defense POW/MIA Accounting Agency are assisting in gathering and identifying human remains, the Pentagon said in a statement Friday. The group is experienced in verifying DNA from long-lost service members, many of whom died as long ago as World War II.

Mayor Richard Bissen accepted Andaya’s resignation effective immediately, the County of Maui announced on Facebook. Andaya cited unspecified health reasons for leaving his post, with no further details provided.
