Dale Strassburger disappeared from the Quad Cities area August 6, 1982

In 1982, 37-year-old Dale Webster Strassburger lived with his parents in Davenport, Iowa. Like thousands of other Quad City residents, he worked at the Rock Island Arsenal.

Dale was a machinist at the plant, which since the 1880s has manufactured ordnance and equipment for the United States Army on a large island in the Illinois segment of the Mississippi River.

After he left work at 12:15 a.m. on Friday, August 6, 1982, Dale was never seen again.

That same day, authorities found Dale’s car on the LeClaire Bridge over the Mississippi River on Interstate 80.

Located a little over 17 miles northeast of the Arsenal, the bridge is in the opposite direction of Dale’s home.

He was reported missing by the Police Department of Le Claire, Iowa, the jurisdiction where his car was located.

There was no sign of foul play in the disappearance, and searches of the Mississippi River and the nearby area yielded no sign of Dale.

At the time he disappeared, Dale — who was born October 10, 1944 — stood 5-feet-9 and weighed 180. He has blond hair and hazel eyes.

He is classified as a missing person with a disability that is physical or mental.
