Maria Magallon wasn't sure how much she should worry when she got the phone call telling her what happened to her son Monday afternoon.
"He came in by helicopter and he was burned pretty badly," she said. "At that time, we didn't know how serious it was."
Her 19-year-old son, Eric, was seriously injured while on the job at the construction site for Table Mountain Casino's new hotel and casino.
The explosion sparked in what's set to be the food court in the new complex.
Eric was rushed to CRMC by helicopter and went straight into a six-hour surgery to treat severe burns on half of his body.
"His back got the third-degree burns and he's got some second, third-degree burns in his shoulder," Maria said. "His leg is all bandaged up. It's very swollen. His hands are wrapped up. They are completely mummified."
