I've always been fascinated by this case, and i'm glad this thread is still active to some degree, i had my ankle operated on a few years ago, and after reading about the case, decided to "investigate" it the best i could using youtube, books, old newspapers articles, and especially anything that raymond johnson had to say (the chicago cold case detective), the big problem with this case is how it was handled by both the police and the press, not only two branches of police couldn't agree on anything, but neither could two coroners offices. the press also went down a rather extreme sensationalist route. so the case was never really handled right.
for me it was such an open and shut case, i've always believed that max fleig was the killer, he admited to it, and he also failed a poligraph, and while it's true that both of these could be questioned, he did end up in jail some years later for the murder of another girl, around the same age as the grimes sisters. that for me is too much of a coincidence. i'd really love to know why fleig was brought in, in the first place.
another thing that i came across and it has been backed up by many sources especially the main detective in charge of this, harry glos believed the girls weren't as saintly as their mother led people to believe, it was believed they spent a lot of time in a bar with much older men, that the older sister had lost her virginity before going missing, n this much more innocent time, the police didn't want to upset the mother or really pull the reputation of 2 young murder victims thru the mud.
this in turn really restricted the case investigation, because if you're scared of going down a certain path, then you're less likely to investigate certain leads. it was a mess, even when they found the bodies, there were dozens of police, reporters, even civilians, just walking around the site where the bodies were found destroying any possible evidence.
does anyone have anything a little deeper on max fleig? why he was brought it? anything?
