I don't. But if memory serves, he said he went back down after everyone was asleep.
The trouble with accepting that is that we know -
JonBenet didn't go to sleep (she was wearing the red turtleneck according to Patsy, and this is unlikely to be sleepwear), she was very unlikely to be asleep in the car because 9 yr old Burke said she helped carry gifts in to the Stine's house and then walked into the house when they got home. She also ate pineapple probably within the hour after they got home.
Patsy likely never went to sleep at all that night (she still had her make up and clothes on from the outing that day)
And I don't believe John took his melatonin and went to sleep either, because his shirt fibres are on JonBenet's genital area and in the too large underpants, meaning he wasn't in sleepwear at the time JonBenet was dressed in them after the assault.
The house lights were all turned off in this time frame of around midnight, probably by an adult who would think of this. Patsy said she usually left on lights around the staircase in case they needed to get up in the night.
So accepting what Burke says about creeping around in the dark with the flashlight after everyone was ASLEEP seems to be pure
confirmation bias of BDI. He never said it at the time and I think he would have stuck to the same story of staying in bed, if there was any chance he did this. I think he has heard his dad say he wanted to play with a toy when they got home, and vaguely remembers playing with it alone while his parents were busy upstairs. Just like he seems to have a false memory of receiving a bike that Christmas, possibly because John invented that a few years later. What other people tell you as a child, can get imprinted as actual memories.
Do we have the parents undressing for bed, and then stopping to put their day clothes back on (red fibres from Patsy's sweater, velvet fibres from John's shirt cuffs) to handle an emergency, and not just attending to JonBenet as they were in their nightwear or simply pulling on a robe?
Burke thought JonBenet had been stabbed. If he thought she had died because of a head wound he had inflicted, why did he invent the stabbing? If he wanted to keep his part in the attack on JonBenet's head a secret, why did he say a hammer was used? Wouldn't he have said she was taken and hit with whatever he actually hit her with, to put the weapon in the attacker's hands? He was guessing. I just can't get on the BDI train. Even if he didn't like JonBenet.
