Winchester RifleMelissa Anderson, Scott Kimball’s 25-year-old girlfriend, buys him a .22-caliber Winchester Model 70 rifle at a Wal-Mart in Thornton for $437.

Anderson, of Thornton, fills out the paperwork, and Kimball lays out the cash.

He told Anderson he would teach her how to hunt, but once she buys the gun she never hears from him again.
