SHASTA COUNTY, Calif. (KRON) — A Bay Area woman has been arrested for allegedly setting the Fawn Fire burning in Shasta County, according to Cal Fire officials.

The woman was identified as 30-year-old Alexandra Souverneva of Palo Alto.

Souverneva was due in court Friday afternoon.

The Fawn Fire is threatening more than 2,000 structures and mandatory evacuations are underway. Cal Fire said at least 25 structures have burned.

“Approximately 4,000 Shasta County residents are evacuated at this time with 30,000 residents affected,” the Shasta County Sheriff’s Office said in a statement Thursday night.

The fire started Wednesday afternoon and has since burned 1,200 acres and is 5% contained as of Thursday.

Wednesday afternoon, Cal Fire personnel and allied fire agencies responded to the brush fire near Fawndale Road, north of Mountain Gate.

Earlier in the day, employees in the area reported seeing a woman trespassing on the property and “acting irrationally”.

Around 8 p.m. while firefighters were battling the blaze, Souverneva walked out of the area and approached firefighters, stating she was dehydrated and needed medical treatment.

Souverneva was taken away from the fire line and medically evaluated and treated.

After being interviewed by Cal Fire law enforcement officers, officers believed Souverneva was responsible for causing the fire. She was arrested then transported and booked into the Shasta County Jail.

Souverneva is also being investigated for starting other fires in Shasta County and throughout the state, Bridgett said.

The case is being submitted to the Shasta County District Attorney’s Office recommending Souverneva be charged with arson to wildland. The charge receives an enhancement due to the declared state of emergency California is in due to wildfire danger.
