A 19-year-old Alaskan girl was killed by her best friend and four other teens after they were promised $9 million in exchange for the proof of murder from an online stranger who was posing as a multimillionaire.

After the anonymous man, who had taken the identity of “Tyler,” offered to pay at least $9 million for the photographic and video evidence of the teenager Cynthia Hoffman’s “rape and murder,” Denali Brehmer (18), reportedly believed to be Cynthia’s best friend, shortlisted four other friends to execute the crime. The victim, who was murdered earlier this month, was found a couple of days later bound with duct tape on her hands, legs, and mouth along with a gunshot wound to the back of her head on a river bank near a hiking trail outside Anchorage. The anonymous man has been identified as Darin Schilmiller of Indiana, who received the vulgar images on Snapchat following the murder, as promised. Two minors were also allegedly involved in the crime.

Brehmer and one other girl have been charged with one count of murder and one count of tampering with evidence, while Schilmiller has been charged with one count of conspiracy to commit murder and multiple counts of sexual assault with a minor.
