Program Features Interviews With the Victim's Father, Sorority Sister and Friends, and a Woman Who Survived An Assault By the Killer Decades Earlier

On a November afternoon in 2003, Dru Sjodin, a senior at the University of North Dakota, was finishing some Christmas shopping when she vanished from the parking lot of her local mall. When authorities arrived at the scene, they discovered a chilling piece of evidence - the sheath of a handheld knife. In a new "20/20," "Nightline" co-anchor Juju Chang reports on Dru's disappearance, the investigation that led police to Alfonso Rodriguez - a local man with a violent history - and the trial that ended in North Dakota's first death sentence in over 100 years that was later overturned.

The two-hour program includes an impassioned interview with Allan Sjodin, Dru's father, who hasn't spoken on national TV since Alfonso Rodriguez's death sentence was overturned. The episode also includes interviews with Deputy Chief Bill Macki and former detective Orie Oksendhal, two of the original detectives on the case; Sven Sjodin, Dru's brother, who was an instrumental part of the initial search efforts to find his sister; Britni Schmalz, Dru's sorority sister; Jean Ann Bienek, Dru's manager at Victoria's Secret; and Shirley Iverson, who survived a previous attack from Alfonso Rodriguez. Additional interviews include Special Agent Chris Boeckers of the FBI; Maria Awes, an investigative journalist; Drew Wrigley, the current North Dakota attorney general who prosecuted the case while serving as the North Dakota U.S. attorney 20 years ago; and additional law enforcement officers and family and friends of the victim. "20/20" airs on Friday, Jan. 12 (9:01-11:00 p.m. EST), on ABC, next day on Hulu.
