The Knox County Sheriff's Office is investigating after discovering a body in a Maquon storage unit on Friday night.
Deputies responded to a complaint of a suspicious odor at 105 E. 3rd St. The owner of the storage unit unlocked and opened the unit, but reportedly told deputies the smell was coming from a dead opossum.
When the storage unit's owner was asked to open a large box in the unit, he told deputies there was a body in it, per a Knox County press release.
Deputies called in the Illinois State Police and opened the box. A decomposing body was found inside. The condition of the body prevented immediate identification.
The owner of the storage unit was detained and later taken to a Galesburg hospital for medical reasons. Charges are pending the results of the investigation.
