I always wonder about cases like this. They had no evidence tying this man to the murder. What motivated them to talk this one witness into testifying against him? Did they "believe" they had the right guy or were they just trying to get guilty verdict of some kind to keep their numbers up? You see similar cases around the country where the only real evidence is a witness who was sure of who it was, but not really. At some point, someone in that chain knows they don't have the right person, but acted to get him convicted anyway.
There is a classic criminal court story on TV drama's of the woman who was talked into testifying that she saw "that" guy do it because they told her they had the right guy. I guess it wasn't fiction. Makes you wonder if they ought to convict one of those people of perjury and publicize the hell out of it. Can the cops/prosecutors be prosecuted for conspriacy to commit perjury?
Also, was the jury allowed to know about the witness's record and the fact that charges were dropped for testifying? I had that happen in a murder case I sat on. One prosecution witness was a whore current in jail and was specifically asked if she received any break in her sentence for testifying. Luckily, her testimony wasn't what we based the conviction on.
