A woman is charged with killing her husband by pushing him off a cliff in Glacier National Park during an argument just a week after they got married.

Twenty-two-year-old Jordan Graham told an FBI agent that she and her husband, 25-year-old Cody Johnson, had been arguing on July 7 as they walked in the Loop Trail area of the park. She said she pushed her husband from the back after he grabbed her arm.

Johnson was reported missing on July 8 when he failed to show up for work. Graham later reported that she had spotted his body.

Graham made an initial court appearance on Monday before U.S. Magistrate Judge Jeremiah C. Lynch on a charge of second-degree murder. She is currently in custody. It was not immediately clear if she had a lawyer.
