“There were reports there may have been some oxygen bottles in the dwelling,” said Lt. John Cromwell Jr., spokesman for the Baltimore County Fire Department.

Fire crews tried to rescue the woman, whom they described as an elderly white woman, Cromwell said. Her name was not released Sunday afternoon.

The fire remains under investigation.

In Anne Arundel, fire crews responded about 7:30 a.m. Sunday to a house fire on the 100 block of Old Farm Court in Glen Burnie.

Firefighters spent about a half-hour getting the fire in the rear of the building under control, said Anne Arundel Fire Battalion Chief Matthew Tobia.

The fire was caused by embers from a pellet stove, which burns compressed wood, igniting material placed too close to the stove, Tobia said.

A couple and their two children escaped without injury.

“Functioning smoke alarms alerted the family, and when they called 911, the alarms were going off,” Tobia said.

This fire caused about $50,000 in damage, he said.

Also on Sunday, crews responded around 3 a.m. to a fire in a two-story, single-family house on the 700 block of 219th Street in Pasadena.

No one was in the residence at the time, and the fire caused about $200,000 in damage, Tobia said.

“This has been determined to be a suspicious fire and remains under investigation,” he said.
