Exorcist: 5 steps to safety after house fire

Two people have died and three others have been treated for injuries after a house fire in an affluent suburb of Los Angeles County, authorities said.

It happened in a residential neighborhood about 40 miles east of downtown Los Angeles, and firefighters were called to the home on Wednesday morning, said Lt.

David Hargrove of the Los Angeles Fire Department.

The blaze destroyed three bedrooms, three bathrooms, two closets, and two garages, Hargrow said.

The victims, all men, were pronounced dead at the scene.

The cause of the fire was under investigation.

Hargroves said a white painted staircase leading up to the property was knocked down.

It appears that the homeowner’s roofing company had neglected to install a ladder that could safely reach the upper level of the house, he said.

Firefighters also were called by the homeowner to the second floor and knocked down a second staircase that had been blocking the main staircase, Harge said.

There was a “serious issue with the structural integrity of the staircase,” Hargroy said.

It took several hours for firefighters to repair the damage.

A neighbor told ABC News that she heard a loud explosion and looked outside to see flames licking the driveway.

“They said it looked like a car had hit the house,” she said.

Harge said the investigation into what caused the fire remained open.
