After conducting a primary search, they found four dogs, one cat and a duck that sadly did not survive the fire.
Firefighters are trying to determine what started a house fire that killed a man Sunday morning.
Alameda County firefighters extinguished the one-alarm blaze in about 10 minutes after arriving in the 17200 block of Via San Ardo at 6:37 p.m., according to fire department spokeswoman Aisha Knowles.
Authorities said search crews found the body of an adult male, believed to be in his mid-70s deceased inside the residence.
Investigators say the fire began in the basement then made its way to the main floor of the house.
The woman was taken to an area hospital, where she died early Sunday, a separate release from the fire department states.
Crews were called to the home on Hartzell Road after neighbors and motorists passing by noticed flames coming from the living room, according to the police report. While the fire was quickly under control, some hotspots remained.
