You can watch the full episode on:

Paramount+: It's available as "48 Hours" Season 36, Episode 70, or sometimes listed as Season 35, Episode 62 or 9.

CBS.com: You can likely stream it directly on the CBS website, though it often requires a Paramount+ subscription to view the full episode.

YouTube: "48 Hours" sometimes posts full episodes or segments on their official YouTube channel, often as part of a compilation of episodes related to a theme like "Social Media Clues."

Keep in mind that while the episode covers the investigation and trial, an editor's note clarifies that some of Chandler Halderson's convictions were later vacated on procedural grounds, though he continues to serve a life sentence for the murder and dismemberment of his parents.
