There are differing accounts of whether the lights were turned on or off at the WHF.
For instance, officer Bews claims that the lights were out in the room upstairs they thought they saw movement in. Jeremy on the other hand claims that the room was brightly lit (his words).
Which was it? Is there any documentation about what rooms were lit and which were not? I would REALLY like to see it!
I think it could be significant.
The killer would have needed to switch on lights to see his/her targets, both in the twins´ room and in June and Nevill´s. I don´t know about Sheila´s room, since I don´t know whether she killed her family - and I don´t know what the killer (from outside) did with Sheila while killing the rest of the family.
Did the killer switch off the lights again in the boys´ room and the main bedroom after the killings???
If Sheila killed herself, the lights would have to be on, right?
OK she could (I have a hard time believing that, but it is not absolutely impossible) have shot herself in the kitchen, where we know the lights were on, then later at dawn have shot herself again in the upstairs bedroom not needing artificial light.
I hope this isn´t too confusing - it can be difficult to express exactly what I want to say in English, but I really think it could tell us a lot if we knew where the lights were on and where they were off.
