ABC 20/20 “He’s Right Behind You” September 26 2025

20/20 launches its 48th season with a chilling two-hour premiere titled “He’s Right Behind You”, airing Friday, September 26, 2025, at 9:00 p.m. ET on ABC. Co-anchor Deborah Roberts leads the investigation into a haunting stalking case that escalated into a shocking murder, tearing apart a seemingly ordinary suburban family.

The Story of Kristil Krug

Kristil Krug, a married mother of three living in a Denver suburb, appeared to be living a peaceful, comfortable life — until a stalker turned that life into a nightmare. The harassment began with disturbing messages and escalated into something more sinister. Kristil, fearing for her safety, believed an ex-boyfriend was behind it all. She turned to police for help, hoping to protect herself and her family.

As investigators became involved, 20/20 gained access to dramatic police body camera footage that documented the family’s fear in real time. These videos show Kristil and her husband Dan Krug working closely with law enforcement to uncover the stalker’s identity. Tragically, that search came too late. Kristil was found brutally bludgeoned and stabbed to death in her garage — the murder unfolding just steps from where her children slept.

A Killer Closer Than Expected

In a devastating twist, the investigation revealed that Kristil’s stalker — and killer — was someone far closer to home than anyone had expected. The episode follows the unraveling of the case, the emotional moments at the crime scene, and the raw grief of a family shattered by violence.

Through exclusive interviews, surveillance evidence, and police footage, 20/20 offers an unflinching look at the dangers of stalking and the gaps that sometimes exist in protection systems meant to prevent tragedies like this.

Tune in Friday, September 26 at 9/8c on ABC for the season premiere of 20/20. The full episode will be available to stream the next day on Hulu.
