Adolph Luetgert was a tanner and a butcher who lived in Chicago. In 1878, he married Louise Bicknese. Over the next few years, Luetgert opened his own sausage business, which expanded to include a five-story factory with the latest equipment, while his marriage went downhill. It was difficult to get a divorce in those days, and besides, Luetgert now had a lot to lose if he achieved one. May 1, 1897 was the last day anyone saw Louise alive. What happened? The evidence was right there in the sausage factory. Read the grisly story of Luetgert and his missing wife at Atlas Obscura.
