Scott Kimball shows up at his girlfriend Lori McLeod’s work with a vial filled with white crystals, claiming he found it at their home.

McLeod decides that her 19-year-old daughter, Kaysi McLeod, who has struggled with meth addiction, needs to talk to police.

After a fight at home, Kaysi goes outside with Kimball and ends up leaving on her bike. She ends up at a Motel 6 in Thornton, where she gets a room with her boyfriend.

Kimball assures McLeod that her daughter just needs time on her own.

Scott Kimball comes by the Motel 6 in Thornton, Colo., where Kaysi McLeod is staying with her boyfriend, Celestino Bovill.

After chatting with the couple in their room, Kimball offers to take Kaysi to her 6 p.m. shift at a Subway in Broomfield.

Kaysi leaves with Kimball in a pickup truck, with trailer attached, that he had stolen from fellow federal prison inmate John Alderman the previous spring.

Kaysi McLeod is never heard from again.

Melissa 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.
