SAN ANDREAS (CBS13) — Deputies are thanking a passerby who rushed into a burning home in San Andreas and helped rescue a woman.

The Calaveras County Sheriff's Office says, just before 9 a.m. Monday, dispatchers started getting calls about an alarm going off near Lewis Avenue in San Andreas. Exactly where the alarm was coming from was unclear at first, but deputies soon zeroed-in on the 300 block of Roberts Avenue.

Minutes later, deputies found a home that was on fire. Heavy smoke was coming from inside, but a deputy started checking to see if anyone was trapped.

After forcing a door open and calling out, the deputy reported hearing a woman's voice asking for help.

The deputy then tried to go inside, but the heavy smoke forced him back. However, as the deputy went back in again, a passerby jumped in to help.

With the citizen's help, the deputy found the woman in a back bedroom and the pair got her out of the home safely.

Firefighters soon put out the flames, which appeared to have started due to a space heater. The woman was treated by medics at the scene, but she was later taken to the hospital.
