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

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. The blast occurred in Esparto, about 40 miles from Sacramento, on July 1, triggering a series of massive explosions, according to the fire department.

The bodies of all seven people who went missing following a fireworks warehouse explosion last week in California have been recovered.
