Sneakers are more comfortable then dress shoes? I dunno about mens dress shoes, but womens hurt my feet so much after awhile, particularly when walking around quite a bit. Also, sneakers would have more traction since the soles tend to have better shape to not slip and slide, don't they? And if someone's walking around in blood, the dress shoes might slip out from under them. Course, it also would make more sense to go bare foot. Easier to wash blood off of bare feet then the bottoms of shoes since shoes tend to have ridges for blood to get stuck/missed in. Or wrap your feet in plastic of some kind, but that would be like sliding down one of those weird plastic water slides people put on the ground in the summer.
...I may or may not read too many mystery books for fun, and have often thought about the barefoot thing.
But that sequence of letters and numbers you mentioned, Cure, sound like a library reference code of some sort. Or maybe a password to a computer, a safe, or something? They don't mean anything to me otherwise, though....
EDIT due to Cureninja: I'm a dumb dumb. I misread BURYING as BUYING omfg. Disregard first paragraph.
I do think it's weird for people to bury sneakers. If they were disposing of evidence it'd make far more sense to burn them since shoes generally are made out of burnable things and it leaves less evidence.
But they probably are the sneakers of a mafia member, I imagine. Hm...
Also, purely theorizing here, but what if the thing from 1916 is repeating itself? Sadie might've been a child that was murdered, or even potentially the child of the woman that banished the ghost. Ghosts ARE known to possess people, so maybe the mafia is composed of people possessed by ghosts? Also, sometimes the people possessed by ghosts don't remember the actions they take, like what Chi asked about someone being mafia without knowing it.
