SAN RAMON, Calif. – Pacific Gas & Electric is expected to plead guilty Tuesday to 84 felony counts of involuntary manslaughter during a court hearing in which the nation's largest utility will be confronted with its history of neglect and greed that culminated in a wildfire that killed 85 people and wiped out most of a Northern California town.The hearing before Butte County Superior Court Judge Michael Deems comes nearly three months after PG&E reached a plea agreement in the November 2018 fire that was ignited by its rickety electrical grid that destroyed Paradise, about 170 miles (275 kilometers) northeast of San Francisco.
