An arson investigation was launched last week, following a fire at Conley Gregory Construction on Old KY 90.
The building was formerly used by Gamble Brothers.
According to Monticello Fire Chief Steve Ferrell, his department was notified of the blaze at 11:31 p.m. on Monday, November 19. He said firefighters remained on the scene until about 2 a.m. battling the fire.
Ferrell said that an equipment building on the site and a nearby open shed which contained a combine were destroyed.
Firefighters determined the cause of the blaze was suspicious and Ferrell said that it was turned over to law enforcement. The arson team visited the scene on Tuesday, November 20.
