Video interviews with John Carter among the files released in the Katelyn Markham case

HAMILTON, Ohio (WXIX) – Case files released Wednesday by the Butler County District Attorney's Office revealed new details in the Katelyn Markham murder case, including video of interviews with her fiancé, John Carter.

Carter pleaded guilty to Markham's manslaughter in June and was sentenced to three years in prison in July. The interviews spanned several years after Markham's murder and disappearance in 2011 and were part of a large file of information prosecutors had on the case.

During an interview in 2011, detectives asked Carter if he would be willing to take a lie detector test.

“We’re doing this now, is that okay?” a detective asked Carter.

“Yeah, I mean, I know I didn't do anything, so everything should be fine,” Carter said.

Carter was interviewed again in 2012, but the interview was not recorded. He was interviewed again on video in 2013 when Indiana State Police came to question Carter after finding Markham's remains in a dump.

“You were here for, say, four hours?” a detective asked Carter.

“I can't think of anything,” Carter replied. “I mean, seriously. I was completely lost. When it was all so real, when the police came and broke into her house and searched everything. I couldn't remember a thing.”

Forty minutes after the interrogation began, Indiana State Police questioned Carter about the discovery of Markham's remains.

“You heard that her body was found. What was going through your mind?” asked a detective.

“I didn't want to cry in front of the cops, ironically,” Carter said. “I tried to keep it to myself. But I was with my mom when they told me. So I confided in my mom more than anyone else, so I went to her and broke down again.”

During a two-hour interview with investigators, Carter was asked if he visited the site where Markham's remains were found after the body was discovered.

“Were you where she was found?” asked a detective.

“No, I don't want to go there,” Carter said. “I don't want to. I don't even want to think about the day she disappeared this year because I don't want to remember her. I don't want to go to that place and think, 'Oh, this is where she died, that's wonderful,' so why would I want to see that?”

Carter is serving his sentence at the Correctional Reception Center in Orient in Pickaway County.
