The story of Kristil Krug is, tragically, often centered on the shocking betrayal and violence that ended her life. Yet, for those who knew her best, her most profound legacy is not the circumstance of her death, but the three kids she loved above all else. Kristil, a brilliant biochemical engineer and devoted mother, poured her energy into creating a joyful and supportive life for her family. Her children were the center of her world, and in the aftermath of their unimaginable loss, they represent the enduring light of her spirit.
While the specific names of her kids have been respectfully withheld from major media reports to protect their privacy during an intensely painful time, what shines through is the vibrant family life Kristil cultivated. Friends and family remember her as a mother who actively nurtured her children’s unique interests, whether that was a passion for the performing arts or a curiosity for technology, creating a home filled with love and encouragement.

A Mother’s Devotion
Kristil Krug’s life was a masterful balance of a demanding career and her unwavering commitment to motherhood. She was married to Daniel Krug in 2007, and together they built a family in the suburban community of Broomfield, Colorado. Her family was complete with two daughters and a son. At the time of Kristil’s death in December 2023, her daughters were 14 and 11 years old, and her son was 8 years old.
Colleagues at Agilent Technologies, where Kristil worked for 19 years, knew her as a sharp and creative project manager, but it was at home where her most important work happened. She shared her own love for modern dance with her daughters and supported her son’s growing interest in technology, ensuring each child felt seen and supported in their individual pursuits.

Those who loved her recall a woman with a “super-analytical mind,” a trait she used not only in her engineering work but also in her meticulous efforts to protect her family when she felt threatened. She maintained a detailed “stalker log” of the harassment she endured, a heartbreaking testament to her determination to shield her kids from danger. Kristil’s cousin, Rebecca Ivanoff, summed it up simply: “Kristil did everything right.” Her actions were always guided by a fierce desire to keep her children safe and secure.
Navigating Life After Loss
The world as these three kids knew it was shattered on December 14, 2023, when their mother was murdered in the family home. The subsequent investigation revealed a truth more painful than any fictional plot: their own father, Daniel Krug, was responsible for the months of stalking that had terrorized their mother and, ultimately, for her killing. In April 2025, Daniel was convicted of first-degree murder, stalking, and criminal impersonation and sentenced to life in prison without parole. This legal conclusion brought a measure of justice, but it cannot erase the profound trauma of losing both parents in such a devastating way.
In the face of this tragedy, the children are being raised by their grandmother, Linda Grimsrud, who has spoken of the daily pain of losing her daughter. The family has also received an outpouring of community support, including a GoFundMe campaign established to help provide for the kids’ future needs and education. Their story continues to be a poignant reminder of the hidden dangers of domestic violence and coercive control.

While their mother’s name has become synonymous with a call for change in how stalking cases are handled, Kristil’s children are the living embodiment of her love, resilience, and spirit—a legacy that will undoubtedly guide them as they build their futures.
