Knoxville, TN – Police say natural gas explosion leveled a home in western Knox County, possibly killing one person and injuring two others in the blast.

The blast, reported at 3:13 a.m. Wednesday, in the upscale Whittington Creek development was heard for miles.

The Knoxville News Sentinel quoted Knox County Sheriff’s Office Assistant Chief Robert Sexton saying one person is believed dead and two others were taken to University of Tennessee Medical Center. Their conditions were not immediately known.

Firefighters on Wednesday morning were searching through the rubble to recover the body believed to be in the basement of the home.

Rural/Metro Fire Capt. Brian Chesney said a buildup of natural gas was the cause of the blast that destroyed the two-story brick home.
