A single mom, who with her young son "lost all their worldly possessions" in the fertilizer plant explosion that devastated West, Texas, is among the first people to sue the plant's owner.

Andrea Jones Gutierrez filed a lawsuit against Adair Grain on Monday. She is seeking up to $1 million.

A fire at the West Fertilizer plant last week caused an explosion that killed 14 people, injured 200 others and destroyed at least 75 homes, according to officials. Investigators are still trying to determine what caused the accident.

Gutierrez lived in the building next to the West Fertilizer plant with her 14-year-old son, who was at church at the time of the explosion.

If Gutierrez hadn't walked out of her apartment complex when she first heard explosions outside, she wouldn't be here today, according to her attorney.

“Everything she and her child owned was completely destroyed,” said Randy Roberts, the attorney who represents her in the lawsuit. “She has physical and emotional injuries, but I’m more concerned about her emotional injuries.”

Two other people who lived in the same apartment complex as Gutierrez died.

“It has been over a week and the company is yet to assume any responsibility, offer assistance or contact those who were affected by this explosion,” said Roberts. “I do expect people to file lawsuits and keep them accountable.”

The company "was negligent in the operation of its facility, creating an unreasonably dangerous condition, which led to the fire and explosion," said a lawsuit filed Friday by insurance companies on behalf of individuals, two churches and businesses including a Chevrolet car dealer and a bakery.

Daniel Keeney, a spokesman for Adair Grain Inc and for its owner, Donald Adair, declined on Tuesday to comment on the lawsuits. "Our focus is on the fact-finding and on assisting the investigating agencies in any way we can," Keeney said.
