One person died after a blaze broke out at a house in Lawrence County early Friday morning, officials reported.

According to Lawrence County Fire and Rescue, units were sent to a reported structure fire in the Crossroads fire district just before 3:30 a.m. on Friday, April 17. The initial dispatch information reportedly indicated one person was trapped inside the home.

Officials said crews arrived on the scene, where the incident commander confirmed heavy fire conditions in approximately 30% of the roughly 3,000-square-foot residence, which had a basement.

Two of the house’s occupants were reportedly able to rescue themselves, but their attempts to rescue the occupant still inside were unsuccessful because they were overcome by extreme heat and smoke conditions.

The fire department said its personnel launched an aggressive interior attack on the blaze while searching for the individual trapped inside the home. Meanwhile, members of the Lawrence County Sheriff’s Office searched other parts of the residence by looking through doors and windows.

According to officials, a deputy spotted someone through an opening in the house, so the interior crew was redirected to that part of the home, found the victim, and brought that person to the front door, where law enforcement and Lawrence County EMS immediately started resuscitation efforts

First responders said the victim was brought to a local hospital, with EMS personnel continuing resuscitation efforts during transport, but the individual later died from injuries related to the fire.

EMS also treated and transported a second occupant from the residence to Southern Tennessee Regional Health System for injuries from the blaze. That person has since been discharged from the hospital, the fire department announced on Sunday, April 19.

The home reportedly sustained extensive damage from heat, smoke, and flames. While the investigation into the cause of the fire is still ongoing, officials said it’s believed to be accidental.
