Last year's deadly Zogg Fire in Northern California was caused by a tree hitting electrical lines owned and operated by Pacific Gas and Electric (PG&E), the California Department of Forestry and Fire Protection said.
The Zogg Fire burned some 56,338 acres in Shasta and Tehama counties from the end of September last year through mid-October.
In total, 204 structures were destroyed, 27 structures were damaged, one person was injured, and four people were killed by the blaze, according to Cal Fire.

The statement added that the investigative report had been forwarded to the Shasta County District Attorney's Office.
PG&E responded to the news in a separate statement Monday evening, saying the company fully cooperated with the investigation but has not seen the report yet.
"The loss of life and devastation in the communities impacted by the Zogg Fire is tragic, and we recognize that nothing can heal the hearts of those who have lost so much," the company said. "We also thank the courageous first responders who saved lives, protected property and worked to contain and put out the fire."

The embattled California utility company recently emerged from bankruptcy. The company has been embroiled in controversy for its connection to several deadly wildfires in California over the past few years.
PG&E said it remains focused on reducing wildfire risk through commitments made in its 2021 Wildfire Mitigation Plan, which includes implementing new electric grid technology, enhanced vegetation management around power lines and other strategies.
"PG&E's most important responsibility is the safety of our customers and communities we serve," the company said. "As the threat of extreme weather continues to impact portions of California, we remain focused on preventing major wildfires and are committed to our mission to safely deliver energy to our customers and communities."
