'20/20' Reports on the Tragic Murder of Molly Watson Just Days Before Her Marriage to Addie

'20/20' Airs Friday, Jan. 7 (9:01-11:00 p.m. EST), on ABC, Next Day on Hulu

Just two days before Molly Watson was set to marry James Addie, her love of seven years, a passing motorist found her tragically murdered on a quiet Missouri road. Authorities soon discovered an elaborate and tangled web of lies surrounding Addie, spun to conceal his biggest secret of all - he was living a double life, both engaged to Watson and married for over 20 years with kids at home. As investigators dug through text messages and other key evidence, the question became how far Addie would go to ensure his two lives wouldn't collide? In a new "20/20," ABC News senior national affairs correspondent Deborah Roberts has the first interview with Melanie Addie, Addie's ex-wife. She opens up for the first time about her marriage and her experience finding out the truth about her husband, which shattered the life she once knew. The two-hour program also includes exclusive interviews with Glen McSparren, the motorist who found Watson's body and may have seen the killer at the scene; Sam Addie, Addie's brother; Sheriff Joe Colston, who helped in the investigation; and Samantha Cohen, Chrystal Graves-Yazici and Tabetha Schilb, wedding vendors who worked closely with Watson and Addie in the days before Watson's murder. "20/20" features interviews with Tim Watson, Watson's brother; Patsy Dent, Watson's aunt; Jodi Lindberg, Watson's cousin; and prosecutors Talley Smith and Katharine Dolin. "20/20" airs Friday, Jan. 7 (9:01-11:00 p.m. EST), on ABC. Watch episodes on demand and on Hulu the day following their premieres.
