On February 20, 2026, at approximately 6:35 a.m., the St. Mary’s County Emergency Communications Center began receiving multiple 911 calls reporting a residential structure fire in the 23000 block of Walnut Drive. Callers described a two-story, single-family split-foyer home with smoke and flames visible and advised that a resident may still have been inside.

Engine Tanker 94, from the Bay District Volunteer Fire Department’s California station, advised they were on the air and requested to run the assignment. Chief 2 granted the request, bringing additional resources to the scene to support suppression efforts. The Working Incident Task Force was alerted at 6:45 a.m.

Chief 2 arrived on scene at 6:47 a.m. and reported fire showing from the second floor of the residence. Command was established, and crews initiated an exterior attack due to the volume of fire and interior conditions that restricted firefighter movement. Division assignments were established for both the lower and upper floors as firefighters worked to contain the fire and assess conditions.

As additional units arrived, crews made steady progress knocking down the fire from the exterior. The large volume of household contents throughout the structure limited interior access and created challenging operating conditions. Rapid Intervention Team (RIT) resources were assigned, and regular personnel accountability reports confirmed all firefighters were accounted for throughout the incident.

At approximately 7:27 a.m., a partial collapse of the front awning was reported. Shortly thereafter, command ordered a transition to defensive operations due to worsening structural instability. Firefighters were withdrawn from the structure, and ladder pipe operations were initiated to control persistent fire conditions, particularly on the upper level and along the front corner of the home.

Around 8:50 a.m., the front porch on Side Alpha collapsed. All personnel were accounted for, and operations continued from a defensive position.

As suppression efforts continued, information confirmed that one elderly female occupant remained unaccounted for, and a vehicle was observed at the residence.

At approximately 9:05 a.m., the fire was declared under control. Due to significant structural instability, particularly in the rear quadrant of the structure, command requested heavy equipment to assist with safe overhaul operations. An excavator was utilized to safely remove unstable portions of the structure.

“This was an extremely challenging incident due to the volume of fire and interior conditions that restricted firefighter movement,” a department official stated. “Our firefighters operated with professionalism and discipline throughout rapidly changing and hazardous conditions. Their focus remained on life safety, accountability, and protecting surrounding properties.”

The cause of the fire remains under investigation by the Office of the Fire Marshal. No firefighter injuries were reported.

This incident serves as an important reminder that maintaining clear interior pathways and minimizing excessive storage of household items can improve fire safety and allow for quicker emergency access. Residents are encouraged to ensure smoke alarms are installed on every level of the home, test them monthly, and develop and practice a home fire escape plan.
