Couple sees rolled-up carpet removed from home as neighbor disappears

A Minnesota man named Gary Herbst vanished in the summer of 2013, and years later investigators made a startling discovery connected to his disappearance. The case gained renewed attention when a couple reported seeing a rolled-up carpet being removed from a neighbor's home around the time Herbst went missing. CBS's "48 Hours" examines the investigation into what happened to Herbst and how the carpet discovery became part of the inquiry. The long gap between Herbst's disappearance and the investigative breakthrough underscores how missing-persons cases can remain unsolved for years before new details emerge. The story explores how neighbors' observations and physical evidence eventually helped authorities piece together the circumstances surrounding his disappearance.
