When eight-month pregnant Laci Peterson mysteriously disappeared from her home on Christmas Eve, a media frenzy ensued. Now, 18 years later, a two-hour “20/20” has new interviews with Janey Peterson, the sister-in-law of convicted killer Scott Peterson, and Pat Harris, Scott’s defense attorney. They discuss Scott’s side of the story, evidence which they claim proves his innocence and their hope to show the evidence to a jury if Scott’s verdict is overturned and he receives a new trial. “20/20” also features Scott’s never-before-heard audio from inside prison. The program dives into the details of the case, including Laci and Scott’s seemingly perfect relationship, the desperate search by family and friends to find Laci, Scott’s secret relationship with another woman and Scott’s trial and conviction for the murder of Laci and their unborn child. “20/20” airs Friday, May 14 (9:01-11:00 p.m. EDT), on ABC.
