I know it's a lot of supposing, and not sticking to the facts, but where did the witness get the idea that his evidence would, in fact, all by itself, convict the suspect? The police must have told him that.
I can't help imagining a scenario where a somewhat reluctant witness was being prodded by police who (over)emphasized how important his testimony was, in an attempt to convince him that he had a duty to testify, but they ended up making him more reluctant, by giving him that much responsibility.
Maybe I'm overthinking, but I still keep coming back to the idea that the witness wouldn't have thought he was the sole means of a person being executed, if the police hadn't told him that.
Also, how often did people hang on the basis of a single witness' testimony, and no other evidence? I realize that back then, juries convicted, and judges pronounced sentence, so the police probably could be fairly certain that, if convicted, the suspect would be executed, but the testimony had to be awfully convincing, absent of any other evidence.
I take that back-- clearly, the police had some reasonable belief that the witness had seen the killer-- not just the last person one of the women was with. But somehow the exact details of what made them so certain are lost.
