In the early hours of 27 August 1979, Marshall County Deputy Sheriff Val Johnson encountered a bright light on patrol — and his patrol car came away with documented damage. What caused it was never settled.

Val Johnson matters because it is a rare physical-trace case with a named officer and documented vehicle damage — yet it rests on a single primary witness and the cause remains disputed.
At about 1:40 a.m., Deputy Sheriff Val Johnson was on night patrol when he saw a bright light in the distance. He turned to investigate, thinking it might be a plane or another vehicle.
Documented
Deputy Johnson’s report of a bright light during patrol is documented.
The patrol car sustained documented damage — a cracked windshield, a bent antenna and a damaged light. Johnson reported losing consciousness during the encounter.
Documented
The vehicle damage is documented; the cause is not established.
The incident was investigated locally, but it rests on a single primary witness and no independent contemporaneous corroboration of the light itself. Explanations range from a collision to a misunderstood phenomenon to an extraordinary cause.
Debated
The cause of the damage and the nature of the light are contested.
The documented damage does not by itself establish what produced it. The incident is a physical-trace case, not a resolved one.
Unverified
Any extraordinary craft or extraterrestrial origin is unverified.
