There is a new delay in the case of a Palo Alto woman accused of starting the devastating Fawn Fire in Shasta County last September. According to reports, a judge on Tuesday declared 30-year-old Alexandra Souverneva mentally unfit for trial. He also put her case on an indefinite hold until she can be evaluated for possible placement in a mental hospital. She appeared in court Tuesday morning and remains in custody at the Shasta County Jail. Souverneva pleaded not guilty to felony arson in late September. Before the fire started near Redding in September, a quarry worker spotted Souverneva nearby. Authorities later arrested her after finding a lighter and carbon dioxide cartridges in her fanny pack. According to court documents, Souverneva was attempting to boil water that had bear urine in it so she could drink it when she allegedly set off the destructive blaze.
