UPDATE: Victim Identified in Fatal Aspen Hill House Fire

The county fire and rescue service identified the woman killed in an Aspen Hill house fire early Thursday morning as Sandra Vidas, 67.

There were no working smoke detectors in the home in the 4700 block of Iris Street, according to a county fire and rescue service news release.

A man who also lived in the home remains hospitalized with non-life threatening injuries, the release said. He has not officially been identified by fire and rescue. An ABC7 report earlier Thursday idenfied the man as Jim Vidas.

The fire is the county's second fatal house fire this year, the release said.

Original post, 12:15 p.m., Thursday, Nov. 3, 2011:

A woman was killed and a man and two firefighters were injured in a house fire in Aspen Hill early Thursday.

The woman’s name has not officially been released.

ABC7 identified the woman as Sandra Vidas and the injured man as Jim Vidas, and posted video from the scene early Thursday morning.

Firefighters were dispatched to the single-family home in the 4700 block of Iris Street shortly before 4 a.m., the county fire and rescue service said in a news release.

They found “significant fire” on the lower level of the home, the main floor and in the attic and found an adult man in the front yard, the release said. He was taken to with serious, non-life threatening injuries, said Capt. Oscar Garcia, a county fire and rescue service spokesman.

Firefighters found the woman in the first-floor bedroom “unconscious and unresponsive,” the release said. She was taken to Washington Hospital Center where she was pronounced dead, Garcia said.

Two of the more than 55 firefighters who responded to the fire suffered minor, non-life threatening injuries, the release said. They were taken to a hospital and were expected to be treated and released later Thursday.

The man and woman were the only occupants of the home, according to initial interviews by fire investigators.

Firefighters on the scene reported intense heat on the bottom floor of the home, leading investigators to consider whether the fire was gas-fed, Garcia said. Gas meters are often found on a home's bottom floor.

"We do believe the origin to be on the lower level, but the cause has not been determined," he said. "We do not believe it to be intentionally set."

The investigation continues.

Fire officials estimate $600,000 in damage to the home, Garcia said.

Firefighters will be in the neighborhood on Thursday checking smoke alarms and handing out fire safety information.
