The Maui County Fire Department on Wednesday is expected to unveil its long-awaited report on the cause of wildfires that killed 102 people and destroyed much of Lahaina more than a year ago, county officials said.

The fire department earlier this week received a written report on the cause of the fire from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives, which the county is relying on for technical analysis, officials said. The fire department is now integrating the information from ATF’s investigative report into the county’s report on the cause and origin of the fire and will share the ATF report in its entirety as an appendix, the county’s communications department said. 

The fire department is expected to present a summary of findings via live-streamed press conference and will release the report to the public at the end of the press conference on Oct. 2.

The announcement comes three months after ATF initially shared its findings with the fire department during meetings in late June. At the time, ATF spokesman Jason Chudy said the ATF report was with Maui County, which would decide when to release it. Later, Chudy said that the ATF was still drafting the report. 

Earlier this month, Chudy said the ATF still hadn’t finished the report and that he couldn’t explain why the report had not been completed or where it was in the drafting process.
