Christine Langford, 24, disappeared on January 17, 1981, near Rockport, California, while camping with her husband Craig. The couple had been living in a motorhome on a remote Mendocino County beach; their motorhome was found abandoned on January 19, 1981. A small inflatable raft and a wooden oar were recovered in the surf near the vehicle, which prompted early theories that the pair might have been swept out to sea.

Despite extensive searches, neither Christine nor Craig has ever been found. Speculation over the years has ranged from an accidental drowning to possible foul play or a staged disappearance, but there is no concrete evidence publicly tying the case to any of those scenarios. The couple had been married only a few months, in September 1980, when they vanished.

Did anyone camp or travel that remote stretch of Mendocino coastline in mid-January 1981 and notice the motorhome, the raft, or anything unusual that could help explain what happened?
