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. Now, just over a year later, the adoptive parents ARRESTED on murder charges.
