Headscratchers / The Shack

• No one apparently saw a figure grab someone's kid and run off? There were adults at the campsite the whole time during Missy's kidnapping so you think someone would have noticed this obvious event.
  • Also, Missy never screamed for help. This would have made it easier for someone to go after her attacker.
• You think they would have done a DNA test with the blood on Missy's dress and found the killer's identity rather quickly. If they already did this, the killer really slipped past the radar.
