witnesses and discovered information that joe's defense didn't have at the trial. >> i got in touch with the two detectives who first responded to this case and confirmed my instinct that there was more to the story than had previously been told. the human body holds eight to ten pints of blood. when tony's body was found, he had two pints of blood left. yet there was no blood or forensic evidence of any kind along the river bank. based in part on that, the two detectives were adamant that tony klann had been murdered elsewhere, not at the river bank as eddie espinoza had claimed. if the location of the murder is different from what the key prosecution witness is claiming, that's a pretty big discrepancy. but the lead detective on the case, leo allen, did not visit the river bank until four or five days after the murder. >> we're involved in other cases. not the only case we have. my goodness. we've got all kinds of work to do.
