"I felt it in my heart that it was my grandson. I did. I really did," said Joseph Peralez Sr., the victim's grandfather.
He tells ABC13 Eyewitness News his grandson is being treated in the burn unit. He described his grandson as a fighter.
"He had an accident back when he was young. He had 80 percent of his body burned. He made it through that, he can make it through this."

And to the family of the man who lost his life in the same fire, James Mangum, he also has words of comfort.
"The pain will always be there. It will never go away, but you can live and there's a way of living with the pain."

This grandfather lost his own son, Joe's father, just weeks before Joe was born.
"I'm proof that you can live," said Joseph Sr.
Now, he says they will lean on that strength again as they pray for a full recovery for their grandson and his co-worker.
