According to case documents, the woman, Kristil Krug, contacted the Broomfield Police Department in October 2023, alleging her ex-boyfriend from 20 years ago was harassing her via email.

Among the email messages suitable for printing: 

  • "i know how to satisfy u"
  • "U dont belong in that big house. U belong with me."
  • "Ill get rid of him and then we can be together."
  • "Ill do it for us Help me get rid of him then we can be together. Just like u want."
  • "U dont want him i know u want me."

Other messages showed the sender was stalking Kristil Krug. One contained a photo of her car in front of a dentist office in which she had an appointment. Another message had a photo that showed her husband getting out of his car at work.

"I know he stopping u from talking to me" was stated in the text of the email.

Kristil Krug had security cameras installed at her family's home after the messages began. The cameras had been turned off the day she died, according to the arrest affidavit.

In the days following her death, Broomfield Police Department detectives learned Krug's husband was only person - aside from Kristil - with the access code to the security cameras. 

They also learned the ex-boyfriend, a resident of Utah, had no evidence of recent messages to Kristil Krug in his devices. The ex-boyfriend also had solid alibis for being in Utah at the time the photos of Kristil Krug and her husband were taken, and at the time of Kristil's death.

Detectives researched the "DNA" of the text messages as well. They learned the messages had been sent through an IP address at her husband's place of employment. 

Lastly, a relative of the couple came forward. The relative told detectives the couple was in the planning stages of a divorce.
