I was thinking about all of those cases that are not discussed about that much on the forum, the cases that are "solved" but the cases seem rather circumstantial and some reasonable doubt is left even if a suspect is convicted or the case is "closed".

For example, the Amber Swartz case, who was abducted in the late 80s and has never been found. In 2009, the case was closed when police announced that a man named Curtis Anderson confessed to her murder and later died in prison. I think there is a possibility that he may be innocent, especially since her body was never found, and that no conclusive evidence ever linked him to the crime. Also, Amber's mother Kim noted that he had a history of false confessions and she thinks the real killer may be still out there.

Another one is the murder of Barbara Jean Horn, who was abducted and killed in her Pennsylvania neighborhood, and the stuffed in a TV box. In 1996, her neighbor Walter Ogrod was convicted of her murder even though there was little evidence to connect him to the crime and didn't match the eyewitness description. Also, I think I read that he had mental disabilities and made a false confession and that another man matched the description of the killer. I think Walter was wrongly convicted and the other man (whose name I can't remember) is responsible.

Any other cases that you can think of like those and do you think they are guilty or innocent?

One comes to mind but is a tad different than what you discussed. It's the David Merrifield case. The main suspect in the case died in 2006 or 2007 and then the police closed the case without naming the person in question. It makes it harder not only not knowing the individual's name, but also his side of the story.

Tommy Lynn Sells, who said he murdered Ashley Freeman and her friend Lauria Bible in 1999 and also Stefanie Stroh in 1987, also falsely confessed to their murders. Jeremy Brian Jones also confessed to killing Freeman and Bible but I think his confession was later proven to be false as well. It's hard telling in those cases who is responsible, since they have eliminated so many potential and somewhat credible suspects.
