I started taking people to the little stretch of road where the "factory" was just as a curiosity to add to my Holmes tours, but we had enough weird nights there that I added it to the ghost tours. This is the place where we saw a woman in a black dress who vanished between two cars, the place where we honestly thought we'd backed the bus into someone, where one night we encountered hawks with dead birds (doves?) in their mouths, and where we once even found some chickens running around. As skeptical as I am, this place can give me the willies. There was also once a light attached to a building that was known to turn itself off and on when Holmes or one of the three victims most likely connected to the location were mentioned. Most nights, I thought it was just a bad circuit, but other nights it worked like clockwork.
But where on this stretch of road WAS the factory, exactly? It would have been built without reliable records (that being the way Holmes rolled), and newspaper accounts at the time weren't terribly helpful, only saying that it was on Sobieski Street, just Northwest of where the railroad tracks intersected Robey (Damen).
That's enough to narrow it down a lot - the stretch of road known as Sobieksi was a little dead-end road even then. On the west side of the road, we've found a half-buried brick that our archaeologist said had an 1890s-type of glaze, making us wonder if it may have been the foundation of the old building. However, a fire insurance map from 1914 shows a set-up that echoes newspaper accounts (a long, one story building with a house at the rear) on the east side of the road. There's a garage on that spot now; many employees have told me it gets awfully spooky in there at night.
Here's the map - it's from 1914, nearly twenty years after the fact. I would have imagined that the building would have been gone by then, but who knows?
1 - the railroad tracks (now a Metra line)
2 - the half-buried brick
3 - a one story building, vacant at the time the map was drawn, roughly matching the dimensions listed in the papers in 1895 (now demolished)
4 - a 2 story house, right about where the paper said a house was (also now demolished)
5 - the vacant/parking area today - the "Holmes Light" was at the back of it.
When the police arrived in 1895, all that was left in the rubbish were some kilns and ashes. Whether they were human ashes was hard to tell - this was still an age when Holmes could say that the bones dug up in the castle were soup bones, and that the blood stains were paint, and expect to get away with it (at least for a while - the fire in August, 1895, destroyed much of the evidence).
It's entirely possible that more bodies were disposed of here than at the "Castle." Aside from some bones and some things that COULD have been used to dispose of a body, not a lot of hard evidence was found in the castle basement. There was a quicklime pit, but it did not appear to have ever been put to use (the lime was clean and white). Some human bones were found, and a large oven, but operating these (as well as the torture equipment which many later authors have believed were found there) in such a crowded building without arousing suspicion would have been a real trick. Besides which, there had been a Tribune article about the secret passages in the building in early 1893. Holmes HAD to know it would be dug up in the event that he was ever caught. And the two weeks they spent digging there gave Patrick Quinlan, his janitor, plenty of time to empty out the rubbish at the glass bending factory.
Holmes certainly was familiar with the area around "Sobieski Street." It's a long way from his South Side stomping grounds, but very close to the Wrightwood St. apartment he rented for Minnie, and a few blocks in the other direction from Franke Wilde's Fruit and Candy store - police at the time were confident that Holmes was Frank Wilde (he mentioned having a place on Milwaukee Avenue in own writings, though in his "confession" he says his attempts to kill employees there failed).
The ghostly activity here brings up a question that's always worth debating: can ghostly activity be evidence of a murder? It sure wouldn't hold up in court, but this may be the only evidence one way or the other about Minnie and Anna Williams, or of Emily Van Tassel, a Franke Wilde employee who is one of the two dozen or so known victims of Holmes.
We'll be running an investigation and recording a new podcast at Sobieski Street soon!
