A woman was killed in a house fire in Chevy Chase on Friday morning, authorities said.

The fire, in the 4700 block of Merivale Road, also sent a man to the hospital with injuries that were not life-threatening, Montgomery County Police said in a post on X.

The identity of the deceased woman was not immediately released.

The fire occurred about 5:45 a.m. and most likely began in the home’s basement, said Pete Piringer, a spokesperson for the Montgomery County Fire & Rescue Service, in posts on X.

When firefighters arrived at the home, Piringer said, an occupant indicated that everyone inside made it out safely. However, a person was later pulled from the home, and despite efforts by paramedics, it was “unfortunately, a fatal fire,” Piringer said.

The cause of the blaze remains under investigation.
