As far as I remember, those were all "reported" to be around or after midnight...? I think the later retracted story of "the scream" and "the grate" were they were heard around 1 am, because that came to be a time often discussed as possibly the TOD long ago. It also fits with the digestion of the pineapple, if JonBenet ate it after the Ramseys returned home.
This "strange lights in the house" story presents a problem for me. If no neighbors "noticed" any lights in the home turned on sometime that night, that doesn't mean they weren't. On the other hand, "someone" moving about the house with a flashlight would seem certainly to be someone involved in the murder.
The neighbor who reported seeing the "strange lights" also said the "usual lights" on in the home were not on that night. So either the Ramseys didn't turn them on for some reason, turned them off for some reason, or someone ELSE turned them off for some reason.
I honestly can't remember now who turned on the basement lights when friends/LE got there. Gosh, good questions. Y'all are just going to FORCE me to go back and read these books yet again, aren't you? :bang:
