The Yuba County Five
On 24 February 1978 five young men from Yuba City drove home from a basketball game in Chico and vanished. Their car was found far up a mountain road; four bodies were found in June, one in a Forest Service trailer that held food they never ate.

The account
Why they drove into the mountains in the snow remains unknown. The fifth man was never found.
The researched reading
Five vulnerable young men stranded in snow, four of whom died of cold. Confusion and exposure explain most of it; why they drove there and where Mathias went remain unknown.
| Explanation | Weight | Why |
|---|---|---|
| A known natural phenomenon | 40% | Four of the men died of hypothermia or starvation after leaving the car stuck in snow far up a forest road; Ted Weiher survived for weeks in a Forest Service trailer, and the deaths follow from cold and exposure. |
| Perception, memory or mind | 22% | Gary Mathias had schizophrenia and was probably off his medication, and three of the others had intellectual disabilities or learning difficulties; a wrong turn, poor decisions and failure to use the trailer’s food and fuel fit this. |
| Undetermined | 22% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| A cultural story | 6% | Retellings dwell on the unused food and missing fifth man and drift into conspiracy. |
| A hoax or fabrication | 5% | Foul play or coercion by someone else has been suspected because of Joseph Schons’s account of people near the car, but he was having a heart attack and nothing else supports it. |
| Something in the surroundings | 4% | Deep snow and freezing nights on the Plumas forest roads made walking out nearly impossible. |
| Genuinely anomalous | 1% | The physical evidence points to cold, confusion and possibly another person, not anything unexplained. |
Official position: Investigators believed the men took a wrong turn and died of exposure; the case remains formally unsolved.
