It has nothing to do with not wanting to believe Isa's parents could harm her..at least not for me anyway. I have been researching true crime for decades and am brutally aware what some parents are capable of doing to their defenseless children.
BUT........
i dont think she was killed in her home by someone she knew. If so the K-9 dogs would have alerted to her cadaver scent instead of tracking an unfamiliar scent taken from the scent sample from Isa's bedroom window sill. The dog tracked from Isa's home over to Cooper Street (which is more likely where the perp got into his vehicle with Isa, imo) and left. The scent was so strong that it gave TPD probable cause for a SW on that home. LE doesnt ask the Mexican LE to put up missing fliers in Mexico of a child that they already know has died in their own home.
And there have also been cases where a stranger took a child from their bedroom and until this case is resolved one way or the other with the real suspect being caught... I have no idea what category to put Isa in. That is like trying to read tealeaves, imo, which I try hard not to do, especially without any facts to support it.
Until I see some valid evidence pointing to who really did this. I will not jump the gun, and assume who the suspect is when "I' really dont know. That is how I have always based my opinions. If some evidence should come to light in the near or distant future, I certainly can, and do change my opinion, but I am not nearly there yet because no evidence at all has been disclosed.
Imo, using an unknown and stating it is Isa's parents is not something I do. I also look at each case individually and not lumped together based on statistics nor what happened in the last case or the first..etc.
Imo, 115 known (and many unknown imo) do kidnap small children Isa's age from their own homes. I have no way of knowing if Isa is or isnt in that 115 who are kidnapped each year.
Now that is just how "I" base my opinions and it has served me very well over the many years being on MBs.
Of course what other posters wish to do on any given case is their entitled rights to do and give whatever opinion they wish.
This only applies to "my" opinions.
IMO
