Families waiting for answers after 7 killed in NorCal fireworks warehouse explosion

YOLO COUNTY, Calif. (KGO) -- It's been almost one week since a Yolo County warehouse storing fireworks exploded days before the Fourth of July, killing seven people.

The families of some of the victims are still waiting for answers after authorities found the bodies of all seven missing people over the weekend.

Authorities provided an update on the investigation Monday morning, but officials didn't give much more information than what has already been released.

The barrage of fireworks that exploded caused the warehouse to collapse along with a wildfire and shook a tiny farming community about 40 miles northwest of Sacramento.

Authorities say they have discovered seven bodies, the same number of people who had been reported missing from the deadly fire in Yolo County.

Two people were treated for injuries following the blast in the town of Esparto, officials said.

The Yolo County Undersheriff and the Esparto Fire Protection Chief both said the State Fire Marshall is leading the investigation but was not at the press conference Monday.

Authorities did confirm that the process to identify the victims recovered from the site through DNA has started. They said the victims would not be identified to the public for at least two days.

Monday morning families waiting almost a week for information posted signs calling for justice and bringing attention to their loved ones.

Officials said they are working to investigate at the site, but have also still been dealing with undetonated explosives that they still have to burn off.

Curtis Lawrence, Chief of Esparto Fire Protection District, said their priority now is supporting the families and making sure the investigation is accurate.

"As much as you all want answers and the family want answers to these things, we have an obligation to make sure that this is done the right way and done thoroughly, so that in the next stages of this incident, as the families begin their recovery process, that we're able to support them with all of the appropriate factual integrity information that they need to recover," Lawrence said. "So we're going to be we're going to do our job to make sure that happens."

Officials were asked about growing reports that a Yolo County Sheriff's lieutenant and a local volunteer firefighter may have ties to the property or fireworks business but they would not confirm any details, again referring to the State Fire Marshal investigation.

They did say one firefighter tied to the site is now on a leave of absence and that no further information would be released.

He operates the business Black Star Fireworks right next door to the warehouse. Cutright said that Devastating Pyrotechnics - which is based in San Francisco - also operated out of the Esparto address.

Records show both companies hold valid licenses with the State Fire Marshal. However, the State Fire Marshal indicated that the facility may have had trouble securing local permits for storing fireworks.

The State Fire Marshall told our sister station ABC10 News in Sacramento, "the local jurisdiction had not permitted this facility."

"The incident in Yolo County is very rare," said State Fire Mashal Daniel Berlant. "We have very strict requirements related to storing explosives and storing fireworks."

The warehouse managed by Devastating Pyrotechnics out of San Francisco, has more than 30 years of experience designing and producing fireworks shows, according to a screenshot of its website before it was taken down.

We reached out to the owner of Devastating Pyrotechnics Kenny Chee, and heard back from his attorney.

In a statement, he said:

"I represent Mr. Chee. Kenny Chee is innocent of any wrongdoing. Until the investigation is concluded, we will refrain from further public comment. Once again, we express our heartfelt condolences to the victims' families and loved ones."

The wildfire covered nearly 80 acres and scorched surrounding agricultural fields, officials said.
