A house fire that fatally injured a firefighter in McCreary County last August was caused by arson, Kentucky State Police said Wednesday.

After a seven-month investigation, state police Arson Investigator Brian Lewis has concluded that the fire was intentionally set, the London KSP post said in a news release.

Whitley City firefighter Arlie "Pooh" Hill III, 37, of Stearns, was severely injured while battling the fire, which occurred on Water Plant Road in Stearns on the night of Aug. 30. Hill had gone into the burning house to see whether anyone was inside.

Hill spent almost two months in the hospital before dying of his injuries.

State police said Lewis is following up on leads in the fire.

Trooper Lloyd Cochran, a state police spokesman, said he could not comment on how Lewis was able to determine the blaze was deliberately set. Anyone arrested in the case could face charges related to Hill's death.

Anyone with information is asked to call the London post at (606) 878-6622.
