22-year-old Rebecca Park was 38 weeks pregnant when she went missing in early November. 3 weeks later her body was found by her father with her unborn child cut out of her womb. This week, police charged her biological mother and stepfather with murdering Park and her baby, but right now, investigators still haven’t found the baby’s remains. Further complicating this disturbing story, police have also arrested Park’s 21-year-old sister and her own fiancé and father of her child. Police aren’t saying if those charges are related in any way to the death of Rebecca and her baby, but they were both arrested within hours of finding her body.
