The fire happened in the 8400 block of Ridglea Avenue on Sunday. Witnesses say before emergency crews arrived, a man who was driving by in a black SUV saw the house in flames and jumped into action. He entered the home and helped the 80-year-old woman to safety. The woman reportedly suffers from dementia.
She was uninjured and her dog was found unharmed in a neighbor's home.
The good Samaritan drove off before anyone could get his name.
