forensic evidence that juries like to see. and the coroner was unable to establish even a cause of death. as for those personal items of kate's that they found in ethan's apartment, those could just have easily been gift. the two were supposedly best friends after all. and to top it off, there was the amazing tale that came with the state's star witness, heather. it's true she helped the warings' investigators found kate's body and agreed to testify against a man she revealed she actually married soon after the crime. but heather was also, as ethan's lawyer was discovering, a gray day world-class liar. >> not only was she a drifter. this was a true con artist with just the most horrid background of anyone i'd ever seen. i mean, a true sociopath. >> david ada was sure that heather on the train to palmetto took one look at kate waring and knew she'd found her ideal next mark.
