UNDATED (CNN) -- Jordan Linn Graham pleaded guilty last week to pushing her new husband over a cliff to his death. Now authorities are releasing their interrogation tapes in which she lies but eventually confesses.
On the tape you can hear, "So he walked out, made a call or something, I don't know if he made a call -- he was in the garage, and I got a text saying he was going and he left."
It was the story Jordan Linn Graham told Kalispell Police in early July to cover her crime that she has now pleaded guilty to: shoving Cody Johnson, her husband of only eight days, off a cliff in Glacier National Park.
In these newly released tapes, graham stuck to her story two days after Johnson disappeared, but she did give police some leads. She said on the tape, "But he always told me this one thing, when his friends came to visit, he would take them to Glacier Park, um, plains or the Hungry Horse Dam."
The next day, in an interview with detectives, she stood by her story but also said she got an email from someone named Tony who told her Cody was dead. The email was traced back to a computer in Graham's parents' house. She sent it to herself.
At one point in the recording, Graham gets comforted by her unwitting mother.
It wasn't until after Johnson's body was recovered that the FBI interviewed graham on July 16 getting her confession. She said on tape, "He went to grab my arm and my jacket and I said no. I'm not going to let this happen this time. I'm going to defend myself. So I let go and I pushed and he went over. And then I took off and went home or got my brother and then went home."
Perhaps the biggest indicator of Graham's guilt all along are her own words. According to court documents, soon after Johnson's body was found, a park ranger commented to Graham that it was in an odd place to which Graham replied quote: "it was a place he wanted to see before he died."
Graham pleaded guilty to second degree murder on Thursday. It was a plea deal in which prosecutors dropped a first-degree murder charge and a charge of lying to investigators.
Her sentencing is March 27. She could get up to life in prison.
