Grim historical bit (for Michael Black)

Below, Michael Black mentioned in a comment a grim little incident from Ste-Catherine Street in 1974. With the help of Kristian Gravenor, reliable historian of the weird and morbid parts of our history, and the BAnQ archive, here’s the story from La Presse and an unnamed English-language paper of July 5, 1974. Kristian also researched the rest of the story.
