Dale Webster Strassburger was 34 when he vanished on June 28, 1982, while driving home from his job at the Rock Island Arsenal. He lived with his parents in Davenport, Iowa, and was expected home that night but never arrived. His 1976 Oldsmobile was found abandoned just 29 minutes after he left work, parked in the eastbound lane on the Le Claire bridge over the Mississippi River—on a route he did not normally take.

Extensive searches of the river and nearby areas turned up nothing. Three years later a witness, during an unrelated court proceeding, offered a highly credible account suggesting Strassburger had been killed; the witness included details not previously public. Investigators could not verify that account, no charges were filed, and no body or conclusive physical evidence has been recovered. The disappearance remains unsolved.

If anyone knew Dale, saw his Oldsmobile in June 1982, or has information about that bridge crossing, please come forward.
