reporter: now that was huge. last time kate was seen with that ipod it was at the gym the day she went missing. now a man kate never met said heather gave him the ipod days after kate disappeared. just to be sure this was in fact kate s ipad, tech expert bill caps got the serial number and within minutes had the proof. i examined the registry file to the computers we had access to that kate used in the past so we had proof positive that was kate s ipod. coming up she said well, they didn t find her, did they? i knew they wouldn t find her. was heather kamp the con artist out of the gate? where was cakate waring? ing?
found out she and ethan were stealing from her. she was like i m going to put you guys in jail and that scared ethan and the whole nightmare began that night because he was not going to go to jail. reporter: so you re saying ethan was the mastermind, not you? yes, yes. reporter: and so after dinner that last night, says heather, they took kate back to their apartment, ethan got her a little high. after a couple of drinks, she was in a very good mood. reporter: there was a big suitcase on the floor. ethan dared her, says heather, get in. she did. didn t see the taser he was holding. he starts tasering her and doesn t stop. by the time he remeevs the taser, she s not moving inside the suitcase at all. he races into the bedroom, grabbing the pillow off the bed, comes back in, pushes me away, unzips the suitcase, takes the pillow, compresses it over her mouth, grabs the wine bottle that is maybe four feet away, takes the wine bottle, crack,
tiny apartment, and then smothered her, shocked her with a taser, drowned her in the bathtub and dumped her body out on wadmalaw island because he thought no one would ever find her there. so did you think you convinced that jury? i thought that the trial went better than i ever could have hoped. reporter: except that is for two things, one, would the jury believe ethan actually killed his best friend kate? and two heather kamp is a liar. heather kamp is jealous of kate. heather kamp is the one stealing. reporter: but heather s testimony did seem to terrify one person, ethan mack himself, and it showed. when he was in the courtroom waiting for the jury too com co back, we have that picture, what was happening with your client? at that point, you know, true
doing. watched a lot of officers and cadaver dogs. ton of folks, whole shebang. reporter: cops had brought heather to lead them to kate waring s body. as a couple of detectives i knew left, i asked them any luck? and they said no and continued driving on. reporter: police called off the search, drove heather back to jail. had she intentionally given them bad information? perhaps nobody would find kate, not the police, not the a-team. and then we got a terrific break by the criminal justice system. mack and kamp both came to the bond hearing and it s done by video. at the bond hearing, mack shows up with this family who were all there to support him, and not only a public defender, but the chief public defender. reporter: wow. yeah. kamp has no one. she has no family, she has no friends, she has no support to speak on her behalf.
crack, i think maybe three times he hits her. he tells me to go inside the bathroom and start the water. reporter: she was terrified, she i cried but i didn t say anything. i didn t know what to do. i didn t know what to say. when he told me to do something, i did it. she filled the tub, she says. he asked me to help pull her in there. i tried, but i can t do it. i start crying, and i throw up in the toilet. why didn t you pull her out of the water? at that point, i the only thing i was thinking about was how am i going to make it out of this house. did you think ethan would kill you, too? why not? who else knows but me? why not? why wouldn t i be next? she helped him put kate s body in the car. watched him dump her out on the island. of course she lied, she admits, when she told ethan she was pregnant. but that was just for the sake of her own safety, says heather.
