A Los Angeles house fire that killed a man and his two children has now claimed the life of the mother.
Fire Capt. Jaime Moore says the woman died at a hospital at about 1:30 p.m. Monday — about nine hours after the blaze at a Sylmar home.
Smoke inhalation is suspected in the death of the woman, her husband, their 12-year-old daughter and 8-year-old son.
Moore says all four had no pulses and weren't breathing when firefighters pulled them from the metal-sided barn that was built in the 1960s as a residence. The man and children were pronounced dead shortly thereafter.
Moore says the building was certified for residential use but lacked fire alarms and the owner could face criminal charges.
The cause of the fire is under investigation, but Moore says arson has been ruled out.
A father and his two children died Monday after they were pulled from a fire at a Los Angeles residence that left the children's mother in grave condition.
The man, believed to be in his 30s, and the children—a girl, 12, and a boy, 8—died at a hospital just hours after being pulled from the burning structure, said Fire Capt. Jaime Moore.
The blaze was reported shortly after 4:30 a.m. in a residential area of Sylmar in the San Fernando Valley, according to fire department spokesman Brian Humphrey.
Firefighters found a two-story barn-like structure consumed in flames.
The four family members were pulled from the building's first floor and rushed to hospitals. All four were unresponsive, Moore said.
The mother was huddled with her son and daughter and the father was in a nearby hallway, he said.
About 35 firefighters put out the flames in about 25 minutes.
The mother, also believed to be in her 30s, remained in grave condition, officials said. The metal-clad building was not equipped with smoke alarms and the family did not appear to have had an escape plan, according to Moore.
Investigators were working to determine the cause of the fire and where it started.
Department of Building and Safety inspectors will determine whether the converted property was properly zoned as a residence.
The first floor had an 800-square-foot living area with two bedrooms and a bathroom, Moore said. The upstairs was used for storage.
Sylmar is nestled in the foothills of the San Gabriel Mountains about 30 miles north of downtown Los Angeles.
