The investigation remains ongoing. Investigators released the names on Saturday of the seven people who were killed in a massive pyrotechnics facility explosion in Northern California that took place days before the Fourth of July.

Shipping records show that Devastating Pyrotechnics imported large amounts of raw chemicals often used to manufacture fireworks.

The girl was fatally injured when a "large illegal fireworks display" set up by a local resident went awry, triggering an explosion, police said.
