An elderly woman died Friday night after her mobile home in Vista's Sierra Vista Mobile Home Park caught fire a little before 9:30 p.m.
Neighbor Pam Boissard called 911 after hearing a loud pop and went to knock on the window.
"The window was extremely hot, there was so much smoke," said Boissard. "I didn't hear any smoke alarms or anything. Someone said that she screamed. No, I think she was gone before police even got here."
The elderly victim was found in the bathroom by firefighters according the medical examiner and later pronounced dead.
"She'd already succumbed to too much smoke and stuff and they couldn't bring her out of it," said Von Schroeder.
The woman has yet to be officially identified by the medical examiner, but neighbors say her name was Helen Stark. They say she was fiercely independent despite a recent stroke that slowed her movement and speech.
“She could walk, but she had to scoop along a little at a time, she couldn't walk like the rest of us can," said Von Schroeder.
Several neighbors in the mobile home park came by Saturday morning to stare at the damage, which was mostly focused in the back portion of the trailer where the bedroom and bathroom are located.
“She was caring, she was always giving cards for birthdays and anniversaries very thoughtful that way," said neighbor Fawn Schroeder.
The sheriff's bomb arson squad was called to the mobile home to investigate and spent several hours at the home, but no official cause was immediately identified.
Crime scene tape was still draped along a back fence nearly 24 hours after the fire started.
Neighbors are guessing an electrical problem is to blame and say it's slightly concerning knowing that they live in similar homes.
