Kentucky State Police say four bodies have been found at the scene of a house explosion and fire in southern Kentucky.

Trooper William Gregory said Wednesday that two people were found inside the home and two outside. Police identified the four as 60-year-old Mitchell Coomer; his 52-year-old wife, Lori Coomer; their 1-year-old granddaughter, Kinley Rodgers; and 32-year-old Steven A. Keltner.

Police said identifications were made using evidence at the scene and from 34-year-old Jason Coomer, Mitchell Coomer's son. Police said Jason Coomer was in the basement on the opposite side of the house when the explosion happened Tuesday and escaped with minor injuries.

Gregory says the cause of the blast remains unknown and under investigation.

The explosion happened at a log house several miles east of Columbia in Adair County.
