Firefighters were dispatched around 1 p.m. Saturday to the 900 block of Polo Avenue, where they arrived to find the house engulfed in flames and one victim already outside on the lawn. Crews pulled the 12-year-old from the burning structure, and a second alarm was called to bring additional resources to the scene. The fire was brought under control at about 1:45 p.m.

Late Saturday, the department confirmed the child had died from injuries sustained in the blaze. The other victim remains hospitalized; officials have not released further details on that person's condition.

"Our thoughts and prayers are with the child's family and loved ones during this incredibly difficult time," Kannapolis Fire Chief Tracy Winecoff said in a statement. "We also recognize the firefighters, law enforcement officers, EMS personnel, and other emergency responders who worked tirelessly to rescue and treat the victims during this tragic incident."

Mutual aid came from a wide circle of neighboring agencies, including the Concord, Atwell and Odell fire departments, Cabarrus County EMS, the Rowan County Rescue Squad and the American Red Cross.

The cause of the fire remains under investigation. Officials have not said whether working smoke alarms were present or how the fire started.

The death is a painful reminder of how quickly a house fire can turn fatal, and fire safety advocates urge families to check smoke alarms, plan and practice escape routes, and close bedroom doors at night. Residents in need of smoke alarms or safety guidance can contact the Kannapolis Fire Department or the American Red Cross, which provides free smoke alarm installation through its Home Fire Campaign.

As investigators continue their work, the loss of a 12-year-old is being felt across a tight-knit community now rallying around the child's family and the responders who tried to save them.
