Edison International energy firm is being investigated for possible link to one of the LA wildfires

Edison International, a multi-billion dollar energy company, is being investigated over a possible link to one of the wildfires burning in the Los Angeles area. 

The $25 billion firm acknowledged in a press release Sunday that it had discovered a downed conductor at a tower close to where the Hurst Fire started on Tuesday evening following a Santa Ana windstorm. But it also said it doesn't know if the damage to the conductor happened before or after the fire, according to the Daily Mail.

The Hurst fire has burned through nearly 800 acres of land since it started. 

As the fires have put pressure on energy, utility and insurance companies, Edison International's market cap has tumbled by $5.73 billion over the past week - from $30.89 billion on January 3 to $25.16 billion today. 

This investigation comes as people are demanding answers as to what caused the worst cluster of wildfires ever seen in the U.S.
