“the guy who later took responsibility knew of at least two details no one else but the cops knew”
Ah, but at least one of the original five suspects knew a detail of the crime that even the cops did not know at the time he stated it, so it would have been impossible for the police to “suggest” it to him as part of a false confession. I’m talking about the theft of the walkman from the victim. Police didn’t know about it, because at the time that the suspect related it, the victim was still in a coma and couldn’t have told the police that she had a walkman that was stolen.
A fascinating case anyway you look at it. Did the victim sustain permanent deficits from the vicious beating she was subjected to?
