CLARKSVILLE, Tenn. (AP) -- Four Tennessee men have been charged with illegally killing deer on property in Fort Campbell, Ky.

The Tennessean reports that Tennessee and Kentucky wildlife agents, as well as federal officials, announced the charges in the poaching case on Friday.

Those charged include 43-year-old Jim Page of Clarksville, 43-year-old Wendell Taylor of Big Rock, and 41-year-old Gregory Crokarell and 45-year-old Curtis Wallace, both of Dover.

While Fort Campbell provides permits for $25 for limited hunting, only archery equipment, muzzleloaders and shotguns are allowed. Officials say the men were using high-powered rifles in an area never open to hunting.

Fort Campbell straddles the Tennessee-Kentucky border, and officials say charges could be forthcoming in Kentucky as well.

They say others are also being targeted in the continuing investigation.
