As you note, the info about the location of the watch and the condition of the floodlights could leak. Here are some thoughts about that, which may be relevant whether the people who sent the ransom messages were involved in NG's abduction or not.
Levin says that the location wasn't standard. Two things that aren't clear to me:
- Was the watch in an unusual location for NG? Or did NG routinely keep or charge the watch in the same unusual location?
- With regard to the floodlights, is it certain they were okay prior to NG disappearing? Or could they have been damaged earlier?
With those open questions,
who might know about the location of the watch?
- People involved in the abduction
- Family members, if they saw the watch when checking the house or heard from LE where it was, or if NG routinely kept the watch in an unusual location.
- People involved in the investigation.
- If NG routinely kept the watch in an unusual location, people who helped out in the house
Who might know about the destruction of the floodlights? If the lights were okay prior to her abduction:
- People involved in the abduction
- Family members who may have seen the lights when checking the house or may have heard about them from LE
- People involved in the investigation
If the lights were damaged prior to the abduction:
- People involved in the abduction (maybe)
- Family members who may have seen the lights when checking the house or may have heard about them from LE
- People involved in the investigation
- People who helped out with the house.
