A teenager in Anchorage, Alaska has been charged with killing her best friend.

In court, 18-year-old Denali Brehmer, showed no emotion as she appeared to admit her role in the elaborate plot to murder her friend Cynthia Hoffman.

According to court documents, Brehmer, 16-year-old Kayden McIntosh, and three others conspired to kill Hoffman for a cash prize.

The $9 million was promised to Brehmer by 21-year-old Darin Schilmiller of Indiana, who was pretending to be a person named Tyler from Kansas and wanted images of the killing.

Court documents say on June 2 Brehmer and McIntosh took Hoffman on a hike where they allegedly bound her with duct tape, before McIntosh shot her in the head and dumped her into a river.

Police found Hoffman's body a day later.

Now, communication discovered between Brehmer and Schilmiller is fueling a second case, in federal court where they face child pornography and exploitation charges.
