A Mysterious Stalker Emerges
Kristil Krug, a 43-year-old engineer and mother of three, began receiving alarming and invasive messages in October 2023. The texts and emails came from someone claiming to be her ex-boyfriend, Jack Anthony Holland, whom she had dated over two decades earlier. The messages started off as awkward attempts to reconnect, but quickly escalated to graphic sexual content, veiled threats, and stalking behavior. One message ominously said, “I’ll get rid of him and then we can be together,” referencing Kristil’s husband, Daniel Krug.
Despite her rising fear, Kristil kept meticulous records of every communication, creating a “stalker log” and reporting the incidents to Broomfield Police. Officers, including Sgt. Andrew Martinez, took her concerns seriously and attempted to trace the origins of the messages, applying for digital search warrants to companies like Google, Verizon, and TextNow. But the responses came too slowly. In the meantime, the messages continued to torment her.
A Family in Fear and a System Too Slow
Kristil’s family members, including her cousin Rebecca Ivanoff — a former prosecutor specializing in domestic violence — later criticized the delay in processing the warrants. Ivanoff believes that had tech companies responded more swiftly, Kristil might still be alive. She had done everything a victim should: documented the threats, contacted law enforcement, even armed herself. But the data that could have revealed the stalker’s identity remained locked away behind corporate red tape.
For weeks, law enforcement chased the theory that Holland, who lived in another state, was the culprit. Kristil herself believed her ex might be obsessed enough to stalk her. The psychological toll on her and her family grew as the messages became more invasive, noting her license plate was expired or that she had been seen at the dentist — indicating real-time surveillance. Still, no arrest was made, and the danger escalated.
A Devastating Discovery
On December 14, 2023, Daniel Krug called police claiming he couldn’t reach his wife. Officers arrived at the couple’s home and discovered Kristil dead in the garage. She had been struck in the head and stabbed in the heart. Initially viewed as another victim in the stalking ordeal, Daniel portrayed himself as a grieving husband overwhelmed by helplessness.
Investigators, still focused on Holland, tracked him down in Utah and prepared to arrest him. But it quickly became clear he had no involvement. He hadn’t been in Colorado, and his cooperation led investigators to reevaluate their assumptions. Then came a crucial break: when law enforcement followed up on their digital warrants under the “exigent” circumstance of a homicide, the tech companies responded in under an hour.
That data traced the stalking messages not to Holland — but to an IP address associated with a government building where Daniel worked.
The Deception Unravels
The revelation shifted the investigation immediately. Detectives discovered Daniel had used burner phones and fake email accounts to impersonate Holland. He sent himself messages to appear as a fellow victim, placed threatening ads online using Kristil’s information, and even created a timeline of events to reinforce the illusion of a third-party stalker. In a final manipulative act, he disabled their home’s security system and used Kristil’s phone to send posthumous texts that would bolster his alibi.
Further investigation revealed Daniel had searched the night before Kristil’s death for information on causing unconsciousness through head trauma. Prosecutors argued that Daniel’s motive stemmed from fear of losing control of his marriage, which had deteriorated to the point of separate bedrooms. He was unwilling to accept Kristil’s desire to separate.
In April 2025, Daniel was found guilty of first-degree murder, criminal impersonation, and stalking. He was sentenced to life in prison without the possibility of parole.
The Push for Legal Reform
Kristil’s murder has sparked calls for legislative change. Her cousin, Rebecca Ivanoff, has proposed “Kristil’s Law,” advocating for mandatory 48-hour compliance from tech companies in cases involving digital stalking and harassment. She believes that the ability to act swiftly could save lives — not just victims, but also protect innocent people like Holland from wrongful suspicion and arrest.
Deputy D.A. Kate Armstrong and digital forensic examiner Randy Philak echoed this concern, stressing the life-saving potential of faster data access. As stalking becomes increasingly digital, the need for real-time collaboration between law enforcement and communications providers has never been more urgent.
Kristil’s family continues to grieve, but they are also determined to see her legacy result in change. Her mother, Linda Grimsrud, spoke of daily pain and the void left behind. But in seeking justice through awareness and policy, her loved ones hope no other family endures the same preventable tragedy.
Conclusion
“The Setup Murder of Kristil Krug” paints a haunting picture of a woman who did everything right but was ultimately betrayed by both her husband and a system that couldn’t keep up. 48 HOURS brings this complex story to light, revealing not just the chilling details of Kristil’s final months, but also the systemic vulnerabilities that allowed her killer to operate undetected. Through interviews, courtroom developments, and digital forensic breakthroughs, the episode delivers a compelling and sobering look at how domestic violence can hide behind a digital mask — and how a delay in data can mean the difference between life and death.
