A 23-year-old Anchorage woman received a 99-year sentence Monday for a 2019 murder that prosecutors say was prompted by a “catfishing” scheme. Denali Brehmer pleaded guilty to first-degree murder in February 2023 for the killing of 19-year-old Cynthia Hoffman near Thunderbird Falls north of Anchorage. According to state prosecutors, Brehmer, 18 at the time, recruited other teenagers to help her bind, sexually assault and fatally shoot Hoffman for an Indiana man posing online as a millionaire.
