KNTV reports the fire broke out at a home in San Ramon Monday morning. A 94-year-old woman and her 71-year-old daughter were inside when it caught fire.
The three teens told Bay Area News Group they noticed the house was on fire while they were skipping class and on their way to McDonald's for breakfast.
"As we're coming down the street, we see smoke rising from this house. Just throwing flames, smoke and everything."
The 71-year-old was able to make it out of the home with minor injuries, but the teenage boys went in to rescue the 94-year-old who was burned in the fire.
Also inside trying to help was the woman's 76-year-old neighbor. He said: "she would have been gone a minute and a half more. ... I don't think she could have survived. I went in there and couldn't see my hand in front of my face." (Via NBC)
And while the students may have been cutting class, their high school principal says he's proud of what they did.
"Exceptionally proud that the three young men would reach out and do something like that because they could've easily just kept walking."
According to KTVU, the unnamed 94-year-old is recovering in the burn unit at a San Francisco hospital. The three boys were also able to help rescue the woman's dog.
