Investigators say they might not be able to determine the cause of the Wednesday morning house fire that killed two middle school students and injured four members of their family.
Jim Carroll, a spokesman for the state fire marshal's office, said Friday, "The damage is so great that there is very little physical evidence to determine the cause."
Kayla Withrow, 13, and Lucy Withrow, 12, who were students at Bath County Middle School, died Wednesday when their two-story home on Vista Lane in Olympia caught fire. Investigators say they found their bodies in the basement; it appeared that the girls fell into the basement from the first floor of the home.
Four other family members managed to escape the home. The girls' father, Virgil Withrow, 56, was in serious condition Friday at University of Kentucky Hospital. His wife, Maryetta, 57; and their daughter Danielle, 15, remained in critical condition. Their son, A.J., 11, was treated and discharged Wednesday.
Meanwhile, Bath County residents announced Friday they will hold a candlelight vigil next week to remember Kayla and Lucy.
The event will begin at 7 p.m. Tuesday at the City of Refuge Church on Sour Springs Road in Olympia, about 50 miles east of Lexington.
