An unlocked door and the DNA of a 4-year-old boy that caught the phantom predator

The unlocked door of Briana: serial killer of Reno: The Murder of Briana Denison

In the early morning of January 19, 2008, a man entered a house in Reno without forcing the door, took Briana Denison sleeping on the couch, and disappeared without waking anyone. The impossible: he left his DNA on the doorknob, untouched money, and did not activate the sleeping dog upstairs. How did a predator attack four times within a kilometer without being captured until his own girlfriend turned him in?

In this episode, we explore how a piece of underwear found in a truck connected three previous assaults to the homicide, and how the DNA of a four-year-old boy confirmed the identity of the serial killer. We unravel the pattern of a plumber who hunted college students, the failures that left him free after the first attack, and the contradiction between his alibi and the testimony of the one who brought him to justice.

Victim: Briana Denison
Date: January 19, 2008
Location: Reno, Nevada, USA
Status: Convicted; death penalty pending (2010)

- Briana disappeared from a couch next to an unlocked door while her friend slept upstairs; her pillow had blood and bite marks.
- Three previous attacks in October, November, and December 2007 within a kilometer shared the same male DNA from the murder.
- James Biela was identified by an anonymous tip nine months later; his girlfriend contradicted his alibi and found women's underwear in his truck.
- The DNA of Biela's four-year-old son matched genetic markers from the scene, confirming biological kinship to the killer.
