Norma Mendez came to see the East Napa house where her young sons and her mother died early this morning.
"I like to face my fears and I think it was best for me to come see it. I know they are with my mom. She's taking care of them," says Mendez.
4-year-old Giovanni Mendez, 12-year-old Matthew Castanon, 58-year-old Aurora Castanon and her boyfriend, 37-year old Eutimo Torres, were all found in the same bedroom. Firefighters say they all died from smoke inhalation.
"Matthew, he was funny, he was 11 and my other little boy was four. He was a character, always in his Spiderman outfits," says Mendez.
Investigators say the fire started in a front living room and the four victims were in a bedroom across the hall. There was a smoke detector in that hall, but firefighters they say they don't know if it was working. The fire was so hot, that the smoke detector melted and fell from the ceiling.
"We did find a smoke detector in the home and haven't determined if it was a working smoke detector. It's the single most important thing you can have in your home to protect you from fire. They work very efficiently and they'll give you an early warning of smoke and give you time to exit your home," says Capt. Scott Sedgley.
Investigators say there is nothing suspicious about the fire.
"I just want to know what happened. Not saying that someone intentionally did it, I just wan to know if was a candle or my mom, who still had a Christmas tree up," Says Mendez.
It could be days before investigators know how the fire started.
