and it s not always right. cullen tracked down the first eyewitness who had identified malcolm and de marchoe as the killers. and he couldn t even look me in the eye. he said, man, i ve been carrying around a burden. man, those boys didn t do that. the man told cullen he shot at the drive-by car as it sped away and claimed that detectives threatened to put him behind bars for firing his weapon if he didn t testify against malcolm and de marchoe. he says that they told him he could be charged with felony murder for firing that gun and that it might have been him that killed karen summers, who knows? now that he was making progress, cullen needed help. so he turned to someone who s been a champion against wrongful convictions for years. tiffany murphy, then the director of the oklahoma innocence project. it wasn t the first time a tulsa case had landed on murphy s desk.
