Waupaca County authorities are investigating a strange littering complaint just outside the city. The sheriff’s office says the complaint is being investigated along Constance Road, the connector road on Waupaca’s northeast side that takes motorists from County Highway “K” to County Highway “E”. It seems someone is dumping energy drink containers in the area, and has been doing so for some time. Officials say “a large quantity” of 5-Hour Energy Drinks, in 1.93 fluid ounce bottles, have been found. The Sheriff’s Office says this has been happening for an “extensive amount of time.” If you have any information regarding this littering, you’re asked to call the sheriff’s office, or Waupaca County Crimestoppers.
