Justice for Missing Brothers Orrin, 3, and Orson, 4

The adoptive parents of 3-year-old Orson West and 4-year-old his brother Orrin, send the boys outside to play just days before Christmas. Mom is inside wrapping presents. The brothers haven't been seen since. The dad was outside collecting firewood when he says he couldn't see the boys. After confirming the boys weren't inside the home, a frantic search began. Just over a year later, the adoptive parents arrested on murder charges.  Now a jury convicts Trezell and Jacqueline West of killing their adoptive son Orrin West.   .Joining Nancy Grace Today:  Marc Klaas - Founder, Klaas Kids Foundation www.klaaskids.org Kathleen Murphy - Family Attorney (North Carolina), www.ncdomesticlaw.com, Twitter: @RalDivorceLaw Dr. Angela Arnold - Psychiatrist, (Atlanta GA) www.angelaarnoldmd.com, Expert in the Treatment of Pregnant/Postpartum Women, Former Assistant Professor of Psychiatry, Obstetrics and Gynecology: Emory University, Former Medical Director of The Psychiatric Ob-Gyn Clinic at Grady Memorial Hospital Sheryl McCollum - Forensic Expert & Cold Case Investigative Research Institute Founder, ColdCaseCrimes.org, Twitter: @ColdCaseTips Bayan Wang, Reporter/Anchor, KMGH-TV, Instagram: @bayanwang, Twitter: @bayanwang See omnystudio.com/listener for privacy information.
