Witnesses at the scene described chaos and shock. Some recounted seeing children crying and running barefoot or in pajamas, with visible burns or injuries and blood on their faces. The explosion felt so intense that many neighbors compared it to an earthquake. ABC7 Los Angeles+1 One witness stated:
“They were just screaming for help, saying, ‘Ow. It hurts! Help me!’ … The little boy without a shirt, just in his sweatpants.” ABC7 Los Angeles
Adding to the urgency of the situation, crews discovered a gas line outside the home that had burned for hours after the blast. Officials from the Southern California gas utility reported they had stopped the leak around 10:45 p.m. that evening.
