The murder trial of a Montana woman accused of pushing her new husband to his death began with the jury seeing a smiling Cody Johnson, looking dapper in a blue shirt and striped tie.
That photograph was replaced minutes later with one of Johnson’s body lying face-down in a pool of water at the bottom of a cliff in Glacier National Park.
There were no witnesses to what happened the night of July 7, when Johnson and Jordan Graham argued over their 8-day-old marriage at a popular spot in the park, Assistant U.S. Attorney Kris McLean told jurors Monday in a Missoula, Mont., courtroom.
“There were only two people on this cliff when the defendant pushed Cody Johnson off,” McLean said.
But by using the testimony of friends and relatives, and the text messages sent by Graham before and after Johnson’s death, prosecutors say they will prove during the trial that Graham, 22, intentionally pushed Johnson from the ledge then lied to family, friends and the police about his death.
Graham has pleaded not guilty to first-degree murder, second-degree murder and making a false statement to authorities.
