In December 2023, 44-year-old Daniel Krug of Broomfield, Colorado murdered his wife, Kristil Krug, in the garage of their home after months of secretly tormenting her with fake messages from a made-up stalker he created using burner phones and multiple online identities. Posing as her ex-boyfriend Jack, Daniel sent harassing emails and photos to both himself and Kristil to convince her she was being watched, all while portraying himself as her protector.
