Situated in Northern California, Yuba County boasts vast wilderness, rugged terrain, and close-knit communities. However, the families of five local individuals were left to grapple with the heart-wrenching mystery of their sudden disappearance on a cold winter night in 1978. Even now, the mystery remains unsolved. On the night they went missing, Bill Sterling, Jack Madruga, Jack Huett, Ted Weiher, and Gary Mathias were affectionately known as "the boys." Their ages ranged from 24 to 32, with four of them having mild intellectual disabilities, while Gary had schizophrenia and a history of violent behaviour.
