A loud, explosion-like sound that was heard across the majority of the county this morning has local officials scratching their heads.
The boom, which occurred at about 9:30 a.m., shook windows in several Lebanon area locations and was heard as far away as Conway, Falcon and Marshfield, but scanner traffic indicated that an officer in the Sleeper area heard nothing.
Laclede County Office of Emergency Management Director Jonathan Ayres told the Daily Record that his office, which is located across from the Laclede County Government Center on Adams Avenue, was shaken by the sound, but its exact cause may remain a mystery.
