HUNTSVILLE, AL (WAFF) - An explosion has claimed two lives and injured several other people at Ultratec Special Effects in Madison County.
Marie Sanderson, of Union Grove, died on the scene, and Aimee Cothran, of Huntsville, died at Huntsville Hospital.
Two victims are in critical condition, and two victims have non-life-threatening injuries.
An injured female was airlifted to UAB with severe burns on her body, an injured man suffered a severe injury to his left knee and face, another man suffered minor cuts and scrapes and was treated and released, and one man suffered minor cuts and scrapes and is still at Huntsville Hospital.
A state lawmaker's daughter was injured in the explosion. The State House of Representatives office and Richie Whorton's office said his daughter, McKenna Whorton, was taken to UAB Hospital in critical condition.
The FBI and the Alabama State Fire Marshal responded to the scene along with local law enforcement.
Investigators said the call came in at 11:19 a.m. and they are still trying to figure out how long it took first responders to get to the scene.
They said it was a fiery explosion so they immediately had to put the fire out and get the victims off to hospitals. After that, they had to make sure the area was safe and that there wouldn't be anymore explosions.
A witness said they were working on Richard Brannum Drive when the explosion happened. He said he was about a mile away from the company and could see the smoke and flames.
They aren't worried about another explosion, but they are making sure the air and water are also safe.
Sergeant Brian Chaffin said they will be testing the air and water every hour, but so far, all the tests have been normal.
Records show this fireworks company has a history of explosions and fires.
The investigation will continue through the weekend to find the cause of the deadly explosion.
"The amount of investigative work that's going to go into this... It's going to be some long hours throughout tonight and tomorrow," said Chaffin. "Possibly into Sunday, not really sure right now. We continue to diagram the scene. Collect what evidence we feel needs to analyzed, and stuff of that nature."
