NOVATO, Calif. (AP) — Senior residents of a San Francisco Bay Area housing complex say they were abandoned by property management during a pre-emptive two-day power outage aimed at warding off wildfires. Residents of the Villas at Hamilton in Novato, north of San Francisco, say they encountered pitch-black stairwells and hallways and elevators that shut down. One woman in her 80s tripped over another resident who had fallen on the landing of a steep stairwell.
