It has been several days and not a sighting on the guy?
The way one article described the vehicle, they implied it was ditched before the shooting.
Plus, I have never met anyone that holds onto berden primed brass, it is as worthless as spent 22lr. (he was shooting Aussie surplus 7.62 ammo)
A large percentage of the county is thick woods and state gamelands sprinkled with old, unused summer cottages, hunting cabins and sheds... King Kong could hide in the forest up here for days and not be found.
