One person is dead after an overnight house fire in Lexington. It happened around 3:45 a.m. Wednesday on Clay Avenue between Euclid Avenue and East High Street. Fire officials say the house that caught fire is made up of three separate apartments inside. We’re told that the left side and upstairs apartments were vacant but someone was living in the right side apartment. Crews say the right side of the first floor was scorched before flames spread to the second floor. Firefighters were able to get the flames under control in about 20 minutes. We’re told the victim wasn’t discovered during an initial search of the building. Officials say the fire burned so hot it burned through the floorboard and the victim’s body fell through the floor. As the morning went on, crews began searching for hot spots and that’s when they found the body in a crawl space underneath the right side apartment.
