A California firefighter was killed in what’s become known as El Dorado Fire in the San Bernardino National Forest. It’s the California fire that was allegedly sparked from a pyrotechnic device at a gender reveal party. It has consumed 20,000 acres already and is 66% contained.

The Los Angeles Times reports:

The cause of the firefighter’s death Thursday is under investigation, and the Forest Service would not immediately confirm whether the death occurred at the scene of the fire.

The San Bernardino County Sheriff’s Department could not say whether the family whose stunt sparked the fire would be charged in the death.
