Joe Pina has been a friend of the Aguilars for 20 years and worked for the couple's son. He wanted to do something when he saw the home burning.
"I went over there and I couldn't help them because everything was in blaze," said Joe.
Joe struggled to get over what he saw.
"There wasn't a way of pulling her out because she was in bad shape," said Joe.
Investigators began their initial investigation on Wednesday. The fire marshal was focusing on the appliances to determine if the couple had any new equipment in the home. Trying to find the answers behind this deadly fire.
