It looks like the case is coming to an end and guilty pleas are pending. From this story in the Wichita Eagle:
The federal case involving more than 60 hunters from across the nation suspected of poaching deer during guided hunts in Kansas appears headed for guilty pleas. Court records listed change-of-plea hearings Wednesday in Wichita for Camp Lone Star owner James Bobby Butler Jr. and his brother Marlin Jackson Butler, who worked as a guide. The brothers from Martinsville, Texas, were the only defendants charged in a case that involved searches in Louisiana, Texas and Kansas. The government alleges out-of-state hunters illegally killed more than 119 deer during the 2005-2008 hunting seasons. Authorities said the hunters paid $3,500 per hunt with archery equipment and $5,000 per hunt with a firearm. The brothers are charged with conspiracy and the unlawful sale and transport of wildlife. James Butler is also charged with obstruction of justice.
