6-6-15 fdl police investigating whether fireworks discharge and mailbox vandalism incidents are related

Fond du Lac police are investigating whether the apparent discharging of fireworks earlier this week is related to a rash of mailbox vandalism incidents.  Assistant police chief Steve Klein says police received two reports of what sounded like either gunshots or fireworks the same night that dozens of mailboxes were vandalized in the city and just outside the city limits.  Police are still looking for the person or persons responsible.
