“The Phantom”: Dateline Reports on Kristil Krug Homicide September 26 2025

by · Published · Updated

NBC’s Dateline presents one of its most disturbing cases on Friday, September 26, 2025, in an episode titled The Phantom. Reported by Josh Mankiewicz, the episode chronicled the tragic murder of Kristil Krug, a Colorado wife and mother of three, and the elaborate deception engineered by her husband, Daniel Krug. What began as a terrifying stalking case turned into a murder investigation that exposed a sinister psychological manipulation.

The episode follows the complex investigation, uncovering how Daniel Krug, a respected government employee, staged a fake stalking campaign to manipulate his wife emotionally, only to kill her when the scheme began to unravel. The story shocked the Broomfield, Colorado community and drew national attention for the disturbing lengths Krug went to in order to control his wife.

Kristil Krug’s Final Weeks and the Stalking Ruse

Kristil Krug’s life began to unravel in the final weeks of 2023, as she reported receiving threatening and vulgar messages she believed were sent by an ex-boyfriend. These messages were highly specific, referencing things only someone close to her could know—her expired registration tags, dentist appointments, and even her routine. Feeling endangered, Kristil began logging every communication and alerted the police.

As the stalking escalated, so did Kristil’s fear. She installed security cameras around her home, began carrying a concealed weapon, and enrolled in firearm safety classes. Unbeknownst to her, the source of her terror was not a man from her past—but her own husband, Daniel. Investigators later revealed that Daniel created fake email accounts and purchased burner phones to impersonate her ex-boyfriend, sending messages meant to terrorize her while simultaneously casting himself as her protector.

The Murder of Kristil Krug

On December 14, 2023, after dropping two of their children at school, Kristil returned home shortly before 8 a.m. Surveillance footage showed no intruders. But inside the garage, Daniel Krug lay in wait. He ambushed his wife, striking her in the head multiple times with a blunt object before stabbing her in the heart. Authorities determined she died from the stab wound.

Following the attack, Daniel attempted to manipulate the timeline. He used Kristil’s phone to disable the home’s security system at 8:15 a.m., sent misleading texts to a detective and her brother, and even covered the garage camera with tape. He left home 30 minutes later than usual, turned off his dashcam, and stopped for coffee to present a façade of normalcy. At 8:56 a.m., he received the very messages he had scheduled earlier that morning from Kristil’s phone, attempting to fabricate an alibi.

The Digital Forensic Trail

Though there was no direct physical evidence linking Krug to the murder—no DNA or blood on his clothes or in his car—the digital evidence was overwhelming. Investigators found that the email account used by the fake stalker had been created from Daniel’s work computer at the Colorado Department of Public Health and Environment. The burner phones used for harassment were bought with a Visa gift card registered to him and were frequently located near his personal phone.

Additionally, Google searches found on Daniel’s devices the day before the murder raised red flags. He had looked up topics like “How hard would you have to hit someone in the head to make them unconscious?” and “When is a head injury a cause for concern?” These disturbing queries revealed premeditation and intent.

The garage camera, which had been operational days earlier, was found covered with tape bearing DNA not linked to Krug. Yet investigators dismissed the possibility of another assailant due to the overwhelming circumstantial and digital evidence against Daniel.

Trial, Conviction, and Sentencing

Daniel Krug’s trial began in early 2025. The prosecution argued that Kristil’s increasing awareness of the stalking ruse threatened to expose Daniel. Realizing that she might turn him in—and that she no longer wanted to stay in the marriage—he decided to eliminate her.

During the two-week trial, prosecutors presented a comprehensive digital trail connecting Daniel to every element of the hoax and murder. His defense team highlighted the lack of physical evidence and questioned the thoroughness of the investigation, but the jury found the circumstantial evidence conclusive. On April 17, 2025, Daniel Krug was convicted of first-degree murder, two counts of stalking, and criminal impersonation.

The next day, Judge Priscilla Loew sentenced him to life in prison without parole, plus an additional nine and a half years. At sentencing, Kristil’s family described the murder as an act of “pure selfish evil.” The couple’s three children were placed in the care of Kristil’s brother and his wife.

The Legacy of Kristil Krug

Kristil Krug was remembered as a brilliant biochemical engineer and gifted dancer who balanced intellect and creativity. Her obituary described her as kind, generous, and devoted to her children. Her family and community mourned the loss of a woman whose life was cut short not by an accident, but by a calculated act of betrayal.

Dateline’s The Phantom not only exposes the cruel actions of Daniel Krug but also gave a voice to Kristil, whose bravery in documenting her stalking ultimately led to justice. The case serves as a chilling reminder of how domestic violence can hide in plain sight and the importance of believing victims even when the threat seems distant or deceptive.
