In December of 2023, police in Colorado responded to a quiet neighborhood in Denver for a welfare check after a 43-year-old woman stopped responding to messages. In the weeks prior, she had been consistently stalked, and plagued with vulgar and terrifying texts and emails – some of which included photos of her and her family. When police checked her home and found her brutally murdered inside, they looked harder at phone records and surveillance footage to finally capture her stalker, and now killer. This is the murder of Kristil Krug.
