Investigation Underway to Find Out What Caused Simi Valley Fireworks Explosion

SIMI VALLEY, Calif. (KTLA) – Authorities launched an investigation on Friday to determine what caused a pyrotechnic device to prematurely detonate during a Fourth of July celebration in Simi Valley, injuring 36 people.

Simi Valley police Cmdr. Blair Summey said that after the early detonation, a group of live canisters fell over like “dominoes.”

One or more of them fired into onlookers, the closest of whom were about 800 feet away.

At least 36 people were injured during the accident at Rancho Santa Susana Community Park on Thursday night at 9:20 p.m.

Among the victims, many suffered minor to severe injuries.

Twenty of the victims were transported to Los Robles Hospital, Simi Valley Hospital and Providence Holy Cross Medical Center, according to Capt. Mike Lindberry, a spokesman for the Ventura County Fire Department.

Eight victims were treated at the scene, and others sought treatment on their own.

Fire officials told KTLA News between 8,000 and 10,000 people were watching the show when the accident happened.
