PG&E said in its Tuesday letter that inspectors later discovered that a hook connecting part of the transmission line and the transmission tower was broken. They also found a flash mark on the tower.
The company also detailed a second outage at another location. That incident was reported a few miles away from the first outage and about 15 minutes after the wildfire started.
When crews went to check the outage a day later, the letter states, they "observed that the pole and other equipment was on the ground with bullets and bullet holes at the break point of the pole and on the equipment."
Meredith E. Allen, PG&E's senior director of regulatory relations, explained that details about the incidents are preliminary and they remain under investigation.
