From the February 28, 1867 New York Times:

“Buffalo–Five dead bodies, two males, two females, and one newborn infant, were found by the Detective Police at the Grand Trunk Railroad depot this afternoon. They were shipped through the American Express Company for Ann Arbor, Mich. The bodies were packed  in flour barrels in a nude state, and had not been dead over a week. The bodies are now being cleansed of flour, and will be exposed for identification to-morrow morning. This city is wild with excitement to know whose relations have been thus desecrated by body snatchers.”
