Nothing causes the true crime community to stir more than a case with the open-ended question of did he? Or didn’t he? Well, except that is, when the question is did SHE?

Does no foreign DNA evidence and strange behavior mean that Dawn Mather had to have been involved in killing her husband? Or does an unidentified fingerprint and tire tracks prove she didn’t?
