From all accounts Patsy wasn't an exceptional housekeeper. She hired help, she had a regular maid. The pine apple bowl was handled by Patsy and Burke. The INSIDE of the bowl would not have fingerprints and it is easy to hand serve yourself pineapple from a bowl and never touch the outside of it. The pineapple was warm indicating it had been left out long enough to come to room temp. Just because you find evidence that the family lived in the house is not evidence that they had anything to do with it.
Whoever cut up the pineapple and put in in the bowl most likely would touch the sides. Burke is big enough (size wise) to help himself to stuff in the fridge or even assist his mom by putting something she hands him on the table.
Yes JB most likely ate from that bowl of pineapple but her prints are not present. All it means is she didn't handle the bowl. She may or may not have served herself.
Tell me what kid didn't get up at night sometime without their parents catching them. We lived a small single story house and all of my sisters and I did together and separately. My parents slept with their door open.
Whose prints are on the bowl may have no bearing on the case.
If you believe John and Patsy could kill their own daughter to protect their son is it so difficult to believe that someone else for the same motive could have killed her.
Many have said the murder was actually an accident. The evidence of over kill her is not the usual in fact it is highly unusual for parents. The intimacy between parent and child even if they were terrible abusers of their child doesn't show such extreme measures as where taken in JB'S case.
The child being papoosed in the blanket does show a feeling of intimacy with the child. A parent even one who severely abuses their child and kills them in a fit have been known to do this as well. If they were the only people who ever did this then you would have some pretty strong evidence for a certain fact. Sadly some weirdos like Karr have been known to do this as they feel real close to their victims in their own sick deluded way. Someone else would also feel close to the child and have some form of intimacy and that is other family members and close acquaintances.
The crime does have elements that can't rule out all possibilities, the immediate family, the friends and other relatives, or some sicko who targeted her.
I wish there was a point value system so I could take each element of the known crime scene evidence and assign each type of evidence a value. Gives points to each of the three groups and come up with a likely candidate.
Not everything has a value of one as some things are more important than others. I put very little value in the fingerprints and others think it is proof.
All I can make of it is that JB ate pineapple before she died.
