"So you're telling me that she asked you to do this," Snuffer said.
"Uh-huh," March said.
"And then you get there and she's asking you to kill her."
"But then you have sex with her."
Snuffer said that, in his experience, there are only two things that drive someone to kill: anger and self-defense. March said he killed her only because she begged him to.
March also said several times during the interrogation that Goble claimed she was going to do something destructive. At one point, he said, Goble asked him to kill someone who was causing trouble for her family.
When pressed, though, March said he did not know what she had planned.
At March's plea hearing Wednesday, Snuffer testified that Goble's hands were still bound to the bed when she was killed. However, according to the transcript of the interrogation, March said he untied her before he began to choke her.
"I could feel her throat crushing under my thumbs," he said, "and she was going, 'Do it. Do it.'"
March said that after Goble died, he put a plastic bag over her head to make sure she was dead and then dragged her to his bathroom and used a wood saw to dismember her. He buried her in his backyard, along with her purse. He said he dismembered her because he could not carry her body.
March said that before he agreed to kill her, he told Goble he would not want a trial and that he would plead guilty if police ever found her body.
Plants said Thursday that investigators could not refute March's claim that he followed Goble to where her Honda was found on I-64. His fingerprints were not found on the car and there is no evidence that he drove it the day she was killed.
Plants said, though, that even if Goble had told March she wanted to die, his actions would still amount to murder under the law.
"At the end of the day, the evidence shows he intentionally strangled and dismembered Kathy Goble," he said. "I don't know if anyone can really say why."
