Oh there are so many inconsistensies...
First they changed statements about what happened after the Whites party. They got home straight from the Whites to stopping at the Stine's to stopping at multiple friends houses to drop off gifts.
Then they change their stories about who went to drop off the gifts at the door and who stayed at the car. Then they do not know who was awake and who was asleep. Burke and JB both being asleep to JB being asleep to no one being asleep as Susan saw JB up and bubbly.
John describing JB as zonked and , quote, "Boy, she is really out" Because I sort of struggled a little bit. It wasn't graceful getting her out, and yet she didn't wake up. And carrying her up stairs, up the back stairs and laying her on the bed." To reading to her after arriving home.
And Burke stating that - "He [Burke] said his sister fell asleep in the car on the way home but awakened to help carry presents into the house of a friend. When they got home, JonBenet walked in slowly and walked up the spiral stairs to bed, just ahead of Patsy. That was quite a difference from the initial and frequently repeated story that she was carried to bed."
And to add here the strange fact that Stine's lived the closet to the Ramsey house but they weren’t among the friends called to the Ramsey house on that morning. After the murder the Stine's just happened to quit their jobs and moved out of state to live with the Ramsey's. Doesn't raise any eyebrows?
Then changing stories about weather Burke went straight to bed or stayed up. And with what toy, if any, was he wanting to play with.
And of course they also changed their stories about what time they arrived back home from the Whites - first they told French that they arrived home at 10, but in later interviews it suddenly became "9-ish". A whole hour, although Stine's lived like 3 minute drive away? Hmm..
Oh, and they did not remember and changed their stories about who did or did not had received a bike that morning for Christmas present. And they changed their stories about Burke owning Hi'tec boots.
Patsy first claimed that in the morning after waking up she got out of bed, went by JB's room and OPENED JonBenet's bedroom DOOR, acknowledges JB is not in her bed, and then goes downstairs and finds the ransom note and rushes back to JB’s room. But later she has said she never opened JB’s bedroom door the first time.
John's story about the basement window has changed multiple times from not knowing about it to breaking it alone to breaking it with Burke being present.
And John booked a flight on his private jet a half hour after carrying JB's body up from basement for a "meeting he can not miss". Then later changed that story during an interview and said they were going home to visit family in Atlanta. - Really, 30 minutes after finding out your daughter has been murdered in your house, you want to go for a visit? Well, they stayed for a couple of more hours and then decided that instead of staying behind to answer questions about their beloved daughters kidnapping/murder they'd rather board their plane and fly out of state.
Patsy did not even recognize her own handwriting from their family photo album. And neither did she remember what size underwear her only daughter wore and owned.
If I remember correctly, there were also some different stories about partially wrapped gifts in the basement - weather Patsy had opened them or someone else in the family.
I wouldn't be surprised if there were more...
