For more than two decades, Jeanne Bishop struggled to understand why her sister and brother-in-law were murdered by an intruder who shot both of them in their suburban Chicago home in 1990. But can she heal by meeting face-to-face with the shooter to get those answers -- and trying to forgive him along the way?
Nancy and Richard Langert were found dead on Palm Sunday by Nancy's father, who went to check on the couple. They were found in the basement of their Winnetka, Ill., home. There was money strewn nearby as if they offered it for their lives. Nancy, using her own blood, drew a heart and a U. Their killer was identified months later as David Biro, a local high school student, who bragged to a friend he did it.
Maureen Maher and "48 Hours" investigated the murder and Bishop's quest to find closure by forgiving the Langerts' killer in "Road to Redemption."
