In 1985, Rachel’s 14-year-old sister, Lori, was found brutally beaten to death in a wooded area. Lori’s ex-boyfriend, Walt, was initially tried for the murder, but the case was dismissed after the trial resulted in a hung jury — and the murder remains unsolved.

Rachel says she and her family were once close with Walt, and he was even best man at her wedding, but she's now "convinced" he killed Lori. She claims his story about where he was the night of Lori's death has changed four times.

Walt vehemently denies having anything to do with Lori’s murder and says Rachel has become “fixated” on him as the main suspect. “I’m innocent,” he says. “Lori’s murder has destroyed me.”
