Dateline NBC “Down the Rabbit Hole” April 25 2026

Dateline NBC returns with Down the Rabbit Hole, airing Friday, April 25, 2026, with Keith Morrison reporting on a complex and unsettling case that began with what appeared to be a home invasion and quickly unraveled into something far more disturbing.

The episode revisits the 2012 murder of Mary Ann Murphy in Humble, Texas. When police responded to a late-night 911 call reporting a break-in, they arrived to find Murphy dead in her home. Early accounts suggested an unknown intruder, but investigators soon began to question whether the story they were hearing matched the evidence at the scene.

As the investigation unfolded, attention turned to Murphy’s teenage daughter, Keri, who initially claimed she had not witnessed the attack. Detectives worked through inconsistencies in her account, leading to a deeper look into her relationship with an older girlfriend, Rebecca Keller. What emerged was a far more calculated and troubling narrative involving deception, manipulation, and a planned attack.

The case took further twists with a false confession and shifting stories that complicated the search for the truth. Investigators ultimately determined that the crime was not a random break-in but the result of a deliberate plot. Both individuals were later convicted and sentenced to prison, bringing a measure of justice in a case marked by its emotional and psychological complexity.

Down the Rabbit Hole explores how the investigation progressed from confusion to clarity, highlighting key evidence, interrogations, and the relationships at the center of the crime. The episode offers a detailed look at how detectives pieced together the truth behind a story that initially seemed to point in the wrong direction.

The episode airs on NBC, with streaming available on Peacock.
