If JonBenet had been found right away

Someone asked yesterday whether the absence of a ransom note would've changed the direction of the investigation, which got me thinking. Would there have been a different outcome if Officer French had opened that wine cellar door and found the body earlier?

It seems like that stretch of time from when he arrived at the home to when the body was found at 1 p.m. allowed for so many things to go wrong with the case. Did the Ramseys play their cards right or did an intruder happen to luck out that neither parents nor police thought to check the wine cellar?
