Authorities are scaling back the ground hunt for a former militia leader accused of firing a gun at Missoula County deputies Sunday before disappearing into the woods near the Idaho border. (Missoula County Undersheriff Mike Dominick says ex-convict David Burgert appears to have had a plan following the exchange of gunfire Sunday along a logging trail after a slow-speed chase near Lolo on U.S. Highway 12. Dominick says police found a second vehicle in the area loaded with ammunition and food and are searching for a third vehicle they believe Burgert might also be using. Officials involved in the search believe Burgert might have been able to escape the area in that vehicle, a 1987 Jeep Wagoneer, Flathead County Sheriff Chuck Curry said. Burgert is the former leader of a Flathead County militia group known as Project 7, named for the number "7" on Flathead County license plates in Montana. Project 7 allegedly plotted to assassinate local officials, go to war with the National Guard and overthrow the federal government.
