According to Zabasearch (public domain information) Lynette Kaufmann lives at 2912 Station Road in Middletown. Looking at the place on Google Earth I’m not seeing any fence at all and I’m also seeing a lot of neighboring homes right nearby.
Lynette is not a responsible dog owner if she’s letting a pack of dogs go wandering around her neighborhood.
It’s possible that the dogs leave the property, but responsible dog owners train their dogs to remain on their own property.
The possible scenarios could just as easily involve a person who intruded onto her property and tried to shoot one or more of the dogs.
